Cline, E. T. and Farr, D. F. 2006. Synopsis of fungi listed as regulated plant pests by the USDA Animal and Plant Health Inspection Service: Notes on nomenclature, disease, plant hosts, and geographic distribution. Online. Plant Health Progress doi:10.1094/PHP-2006-0505-01-DG.

AbstractTo prevent the entry of exotic fungal pathogens, the Animal and Plant Health Inspection Service (APHIS) of the U.S. Department of Agriculture (USDA) has compiled a list of regulated plant pests of concern to the U.S., including more than 50 species of fungi that might cause serious economic or environmental damage. The fungi on the APHIS Regulated Plant Pest List represent some of the most significant threats to U.S. agriculture. For each of these fungal species, a synopsis was prepared that presents notes on nomenclature, disease, plant hosts, and geographic distribution. The following scientific names should be updated: Cercospora batatas (Pseudocercospora timorensis), Chrysomyxa ledi var. rhododendri (Chrysomyxa rhododendri), Crinipellis perniciosa (Moniliophthora perniciosa), Phacidiopycnis pseudotsugae (Allantophomopsis pseudotsugae), Pucciniastrum areolatum (Thekopsora areolata), and Stereum hiugense (Xylobolus hiugensis). Nomenclatural controversies are discussed for some species, including Diaporthe mali and Monilinia fructigena. Changes in nomenclature often reflect advances in taxonomic understanding, resulting in transfers to a different genus, modifications of lists of taxonomic synonyms, or establishing anamorph/teleomorph connections. These changes can have important implications for accurately determining the geographic distribution and host range of a fungus. Accurate information about scientific names, geographic distribution, and plant host range is essential in determining pest risk and in preventing the introduction and spread of invasive fungal pathogens.

IntroductionPathogenic fungi annually cause billions of dollars of damage to agricultural crops, roughly equal in value to that caused by insect damage. It is critical that agricultural production as well as non-cultivated plant resources be protected by preventing the entry of invasive fungal pathogens. The Animal and Plant Health Inspection Service (APHIS) of the U.S. Department of Agriculture (USDA) has compiled a list of plant pests of quarantine concern to the U.S., including more than 50 species of fungi. The APHIS Regulated Plant Pest List includes pests from the U.S. Code of Federal Regulations (7 CFR 300-399), pests frequently intercepted at U.S. ports of entry, and pests that otherwise might cause serious economic or environmental damage. The list provides an official foundation for policy decisions surrounding trade and plant quarantine issues. As such, the list plays a critical role in safeguarding U.S. agriculture and protecting native ecosystems.

The fungi on the APHIS Regulated Plant Pest List represent some of the most significant threats to U.S. agriculture. It is important to ensure that accurate information is accessible to all stakeholders. We have prepared a synopsis for each of the fungi on the APHIS Regulated Plant Pest List giving scientific names, connections to alternate states (i.e., anamorph/teleomorph), and taxonomic synonyms based on the most recent taxonomic publications. This information is critical for accurately determining the geographic distribution and host range for a fungus. For example, a fungus may be reported only under the name of a synonym in some regions. Some fungi may occur on one host as an anamorph but on an alternate host as a teleomorph. This is particularly common for the rusts, which represent nearly half of the species on the APHIS Regulated Plant Pest List.

Three of the fungi on the APHIS Regulated Plant Pest List are also listed as APHIS Select Agents: Peronosclerospora philippinensis, Sclerophthora rayssiae var. zeae, and Synchytrium endobioticum. Select Agents are chosen based on their potential to cause substantial harm to human, plant, or animal health. They are tightly regulated by APHIS in keeping with their mandate to prevent, prepare for, and respond to acts of bioterrorism and other public health emergencies that could threaten either public health and safety or American agriculture.

We have limited the scope of this paper to the fungi included on the APHIS Regulated Plant Pest List, but many additional plant pathogenic fungi not already in the U.S. and not on the APHIS Regulated Plant Pest List are also of quarantine concern. The APHIS Regulated Plant Pest List must periodically be revised to reflect updated information or changes in the status of pests (e.g., geographic distribution), and name changes for taxonomic or nomenclatural reasons. In some cases, the listed fungus may be a harmless saprobe or endophyte, or occur only on insects (e.g., Beauveria spp., Entomophthora spp., Cordyceps spp.). Other plant pests may already be widespread in the United States, so that quarantine is pointless. We have consciously refrained from expressing any judgement as to the appropriateness of including each of these fungi on the APHIS Regulated Plant Pest List. We have prepared these synopses in the hopes that, by providing updated nomenclature, host range, and geographic distribution, this information will establish a foundation for future revisions of the list.

A web-based publication is particularly appropriate for this subject, because it makes it possible to direct the reader to additional information — in particular, to the continuously updated nomenclature and fungus-host records available from the Systematic Botany and Mycology Laboratory (SBML) website of the USDA Agricultural Research Service (2).

To ensure accuracy and clarity of communication, scientific names are used to designate the pests included in the APHIS Regulated Plant Pest List. Scientific names are regulated by a codified set of rules, the International Code of Botanical Nomenclature (3). Scientific names may change occasionally, often to


http://www.aphis.usda.gov/programs/ag_selectagent/index.html


conform to changes in taxonomic judgment or recent scientific discoveries about the relationships of these fungi (e.g., Moniliophthora perniciosa). Names may sometimes change as a result of changes to the International Code of Botanical Nomenclature (ICBN) voted upon by the International Botanical Congress. Name changes sometimes can result in confusion; access to critical information may be lost when literature or data records are associated with incorrect names.

The SBML has developed a database of accepted scientific names and their synonyms of fungi of importance to agriculture. The accepted scientific name is linked to known nomenclatural or taxonomic synonyms, which allows the user to search under all present and historical names for data about geographic distribution, plant host associations, herbarium specimens, and scientific literature references. Another website providing information about fungal accepted scientific names and synonyms is Index Fungorum (1).

In updating the SBML nomenclature database, the authors encountered several names on the APHIS Regulated Plant Pest List which should be corrected to reflect currently accepted scientific names. These include Cercospora batatas (Pseudocercospora timorensis), Chrysomyxa ledi var. rhododendri (Chrysomyxa rhododendri), Crinipellis perniciosa (Moniliophthora perniciosa), Phacidiopycnis pseudotsugae (Allantophomopsis pseudotsugae), Pucciniastrum areolatum (Thekopsora areolata), and Stereum hiugense (Xylobolus hiugensis). We also encountered cases where inadequate information or controversy surrounding nomenclature could result in confusion. For example, see Diaporthe mali Bres. 1902, not to be confused with Diaporthe mali Miura 1915, a synonym of Diaporthe eres Nitschke 1870. There is also considerable confusion concerning Monilinia fructigena and related brown fruit rots.

For each fungus on the APHIS Regulated Plant Pest List, we provide a synopsis of the currently accepted scientific name (in green font), all known nomenclatural synonyms (preceded by ≡), and all known taxonomic synonyms (preceded by =). Dates of publication and discrepancies of author citation have been verified by consulting historical literature, i.e., the original protologue or diagnosis, when possible. Homonyms and invalid names are denoted by brackets. The format generally follows that of the SBML nomenclature website. Notes on nomenclature, including citations of relevant Articles of the ICBN, are provided for additional clarification. Sources consulted to produce nomenclatural reports are cited at the end of each entry, as are those associated with controversial taxonomic judgments.

Brief notes on geographic distribution, substrate, disease characteristics, and plant hosts provide a summary of information available for the fungus, based upon data from the accepted name and all its synonyms. The American Phytopathological Society (APS) Common Names of Plant Diseases were

followed when available. These notes represent data available at the time of publication. For the most recently updated information, and documented links to more detailed explanations, we refer the reader to the SBML nomenclature website where searches can be performed using the accepted scientific name of a fungus and any of its synonyms.

Within the document, links allow the reader to move from the Table of Contents to listings for individual fungi. Fungi are listed alphabetically by accepted name. Names on the APHIS Regulated Plant Pest List that differ from the currently accepted name are listed alphabetically with a link to the appropriate accepted name (in green font). When an additional species name has been listed for comparison to a species on the APHIS Regulated Plant Pest List, the name for comparison is not included in the Table of Contents, and the name is listed in black font. Links to SBML webpages providing diagnostic information and other additional information are provided for some species.

We hope that by combining the latest information on these important plant pathogens within a single document, these synopses will prove useful in the effort to prevent the entry of exotic pests and combat their spread.

Aecidium mori

Geographic Distribution: Asia.Substrate: Leaves, petioles, branches, buds.Disease Note: Rust. Only the aecial state is known (Fig. 2). The aeciospores are able to reinfect the host and therefore function as a uredinial state.

Host Range: Broussonetia spp. and Morus spp. (mulberry, Moraceae).Fungal Order: Uredinales

Aecidium mori (Barclay) Barclay 1891≡Caeoma mori Barclay 1890≡Peridiopsora mori (Barclay) K.V. Prasad, B.R.D. Yadav & Sullia 1993≡Uredo mori (Barclay) Sacc. 1891

Notes: This name was originally published as Aecidium mori Barclay n. sp. (i.e., as a new species), but this taxon was later determined by Barclay to be identical to the previously described Caeoma mori Barclay. Barclay broadened the species concept to include a fungus on Ficus palmata, which was subsequently referred to Uredo fici Cast. by Sydow in 1907 (erroneously cited as (Barclay) Syd. 1907). The new combination Peridiopsora mori (Barclay) K.V. Prasad et al. 1993 has not been widely adopted by other authors. Although Prasad et al. (1993) list Cerotelium fici (Cast.) Arthur as a taxonomic synonym (host Ficus spp.), this is generally considered to be a distinct species.

[Pseudophacidium decorticans Rehm 1885] Note: Invalid name.

Notes: Di Cosmo et al. (1984, 1983) list Phacidium pulverulentum Schmidt:Fr. 1817 as a taxonomic synonym, acknowledging that it may be the earliest valid name for this fungus. The authors rejected the use of this name due to the ambiguity of the diagnosis and the lack of authentic or type material.

Beauveria spp.

Note: All species of Beauveria occur on insects. Some species are utilized as biological control agents. While their entry into the country could have ecological consequences, members of this genus are unlikely to act as plant pests. It seems inappropriate to include this genus on the Regulated Plant Pest List.

Fungal Order: Hypocreales

Ceratocystis fimbriata

Geographic Distribution: North America, South America, Caribbean, Pacific Islands, Asia, Africa (South Africa, Congo), Australia, New Zealand. Numerous reports exist of occurrence in the USA on Ipomoea batatas, including Alfieri et al. (1984), French (1989), Raabe et al. (1981), and Shaw (1973).Substrate: Woody branches and stems, roots, leaves, tubers.Disease Note: The American Phytopathological Society (APS) common name is coffee canker, also known as black rot of sweetpotato, mouldy rot of rubber, trunk and branch canker of other fruit and nut trees, canker stain of forest trees, canker and wilt of pimento.Host Range: Principal host: Ipomoea batatas (sweetpotato, Convolvulaceae). Additional hosts in multiple plant families; some host specialization exists among strains. The fungi on Theobroma cacao (cacao) and Platanus spp. (sycamore) are now considered distinct species (Engelbrecht & Harrington 2005).Fungal Order: Microascales

Notes: Chen transferred this fungus to the new genus Stilbechrysomyxa, but Cummins & Hiratsuka (2003) argue that further confirmation of placement in this segregate genus is required. Spaulding (1961) reported that the potential aecial host Picea smithiana could be infected through artificial inoculation, but Vattiprolu & Agarwal (2002) list the aecial and pycnial state as unknown.

Notes: Savile (1950) published the new combination Chrysomyxa ledi var. rhododendri based on Uredo rhododendri DC 1815 (an anamorph), without description of the teleomorphic state. Savile (1955) later considered this to be an invalid combination (nom. nud.), but the name was validly published based on Uredo rhododendri DC. 1815. The 1950 name must be considered an anamorphic name in a teleomorphic genus, and the teleomorphic 1955 name is an illegitimate later homonym, based on the current Code (Art. 59.5 N.1, Art. 59.6 ex. 7). Similarly, Schröter (1878) published the combination Coleosporium rhododendri (DC) Schröt. based on the anamorph, mentioning the teleomorph but not describing it.

Cronartium flaccidum; Alternate State (Anamorph): Peridermium cornui

Geographic Distribution: Europe, Asia.Substrate: Stems.Disease Note: Scotch pine blister rust; resin canker. Heteroecious rust. Infection through foliage or stem wounds.Host Range: Aecial host: Pinus spp.; telial hosts: Asclepiadaceae, Paeoniaceae, Scrophulariaceae.Fungal Order: Uredinales

Cronartium flaccidum (Alb. & Schwein.) G. Winter 1880 [1881]≡Sphaeria flaccida Alb. & Schwein. 1805

Notes: This is the type species of the genus Cronartium. Hantula et al. (2002) showed that Cronartium flaccidum and Endocronartium pini (DC.:Pers.) Y. Hirats. 1969 are closely related despite displaying heteroecious and autoecious life cycles, respectively. We retain the distinction for now, following Hiratsuka (1969) and Hiratsuka (1992).

Alternate State (Anamorph): Peridermium cornui Rostr. ex Kleb. 1890

Notes: This name was originally used by Rostrum (1889) but with no description, therefore Peridermium cornui Rostr. 1889 is an invalid name, nom. nud. Klebahn (1890) validated the name, describing this species as the anamorph of the heteroecious rust Cronartium flaccidum (as Cronartium asclepiadeum). Klebahn (1890) amended the concept of Endocronartium pini (as Peridermium pini) to include only the autoecious pine rust.

This fungus is morphologically indistinguishable from Botryosphaeria dothidea but causes different disease symptoms.Host Range: Principal host: Pyrus pyrifolia. Additional hosts: Pyrus spp., Malus spp., Chaenomeles japonica (Rosaceae).

Guignardia pyricola (Nose) W.

Note: The basionym reference was given with a page range, not the exact page, therefore this name is not validly published (Art. 33.3). This constitutes an unconventional use of forma specialis (f. sp.) for a fungus from multiple plant host genera (Smith 1992).

Notes: The status of this fungus is controversial. It is clear that Guignardia


http://www.bgbm.org/iapt/nomenclature/code/SaintLouis/0065Ch7OaGoNSec1a60.htm


pyricola belongs in the genus Botryosphaeria, but no valid name has been published. The only name for this fungus in Botryosphaeria is Botryosphaeria berengeriana f. sp. pyricola, but the forma specialis has no nomenclatural status (Art. 4 Note 3), and the basionym citation was incorrect making B. berengeriana f. sp. pyricola an invalid name. We have no other option than to list this taxon under the name Guignardia pyricola until its status has been resolved. Some authors consider it a taxonomic synonym of Botryosphaeria dothidea; it is morphologically identical to Botryosphaeria dothidea but causes distinct disease symptoms (Smith et al. 1992). The anamorph is an unnamed Fusicoccum. If, after reexamination, this fungus is recognized as a distinct taxon, a new combination in the genus Botryosphaeria should be published.

Monilinia fructigena and Related Brown Fruit Rots.

Monilinia fructigena is one of four related fungi that infect members of the Rosaceae, causing brown fruit rots of considerable economic importance. There has been some taxonomic confusion between the four species Monilinia fructigena, Monilinia fructicola, Monilinia laxa, and Monilia polystroma Leeuwen 2002. The latter species was described based solely on the anamorph. Monilinia fructigena is widespread in Europe, rarely infects blossoms and twigs, and occurs primarily on apples (Malus spp.), pears (Pyrus spp.), and other pome fruit trees, although it is also found on Prunus spp. The brown fruit rot of Japan, previously considered to be M. fructigena, is a distinct species based on recent morphological and molecular studies, and has been named Monilia polystroma Leeuwen 2002. Monilinia fructicola is widespread in North America, commonly infects blossoms and twigs in addition to fruits, and occurs primarily on Prunus spp., but also on apples, pears, and other pome fruits in the Rosaceae. Monilinia laxa co-occurs with the other brown rot fungi, primarily in Europe and the Pacific Northwest of North America. M. laxa resembles M. fructicola in infecting blossoms and twigs in addition to fruits, but has a host range similar to M. fructigena, occurring more frequently on Prunus spp. but also on other members of the Rosaceae (see Batra 1991 for more details).

Monilinia fructigena;Alternate State (Anamorph): Monilia fructigena

Geographic Distribution: Europe, Asia (China), South America (Uruguay, Brazil). American literature references to Monilia fructigena previous to 1928 probably refer to Monilia fructicola Batra 1991. Reports of Monilia fructigena in Japan probably refer to Monilia polystroma Leeuwen 2002.Substrate: Primarily fruits, rarely blossoms and twigs.Disease Note: The APS common name is brown rot, blossom blight, and fruit rot. Overwinters in mummified fruits.

?= Torula fructigena Pers. 1796= Oidium fructigenum Kunze & J.C. Schmidt 1817= Oospora candida Wallr. 1833= Oidium wallrothii Thüm. 1875

Note: The earliest potential description of the anamorph (conidial state) of this fungus was made by Persoon in 1796, under the name Torula fructigena. Harrison (1933) found Persoon’s 1796 description insufficient to distinguish among the other Monilinia spp. on Rosaceae (Batra 1991). In 1801 Persoon described the conidial state of the fungus as Monilia fructigena (subsequently sanctioned by Fries), later transferring it to the genus Acrosporium as Acrosporium fructigenum (Pers.) Pers. 1822. Wallroth placed it in the genus Oospora as Oospora fructigena (Pers.:Fr.) Wallr. 1833. Boudier transferred it into the genus Stromatinia as Stromatinia fructigena (Pers.:Fr.) Boud. 1907, thereby creating an illegitimate later homonym of Stromatinia fructigena Ritz. Bos 1904 (=Monilinia fructicola (G. Winter) Honey 1928). In addition, Oospora candida Wallr. 1833, Oidium fructigenum Kunze & J.C. Schmidt 1817, and Oidium wallrothii Thüm. 1875 are considered to be taxonomic synonyms (Batra 1991).

In 1893, Schröter transferred Persoon’s anamorphic fungus to the holomorphic genus Sclerotinia, without a description of the teleomorphic state, creating the anamorphic name Sclerotinia fructigena (Pers.:Fr.) J. Schröt. 1893. Aderhold & Ruhland (1905) added a description of the teleomorph to the name, thereby creating an illegitimate later homonym, Sclerotinia fructigena Aderh. & Ruhland 1905 (often cited as (Pers.) Aderh. & Ruhland 1905) (see Kohn 1979 p. 408-409 for more detail).

In 1936, Honey used the combination Monilinia fructigena, without description or reference to a description (invalid name, violating ICBN Art. 41.3). In 1946, Whetzel was the first to validly publish the combination, cited as





Monilinia fructigena (Aderh. & Ruhland) Honey 1936, with reference to the description of the teleomorph provided by Aderhold & Ruhland for Sclerotinia fructigena Aderh. & Ruhland 1905. Because S. fructigena Aderh. & Ruhland 1905 is an illegitimate later homonym of S. fructigena (Pers.:Pers.) Schröt. 1893, the combination is properly cited as Monilinia fructigena Honey ex Whetzel 1946 (see ICBN Art. 58). This is the currently accepted holomorphic name for this taxon.

= Monilia cinerea f. americana Wormald 1919

Note: The teleomorph of this fungus was first described on mummified peaches from Pennsylvania as Ciboria fructicola G. Winter 1883 (Batra 1991). It was transferred to the genus Sclerotinia by Rehm (Sclerotinia fructicola (G. Winter) Rehm 1906) and to Monilinia by Honey as Monilinia fructicola (G. Winter) Honey 1928, the currently accepted name. Sclerotinia americana Norton & Ezekiel 1924 is a taxonomic synonym (Batra 1991).

In 1902, Norton observed the teleomorphic state of a Monilia sp. on Prunus fruits from Maryland and named it Sclerotinia fructigena Norton 1902, creating an illegitimate later homonym of Sclerotinia fructigena (Pers.:Fr.) J. Schröt. 1893 (anamorph of Monilinia fructigena). The existence of this homonym may have added to the confusion between Monilinia fructigena and Monilinia fructicola.

Before the American brown fruit rot was described as Monilinia fructicola (G. Winter) Honey 1928, American collections were frequently reported under the name Monilia fructigena. After 1928, the invalid name Monilia fructicola was used, despite the lack of a formal description of the anamorph (Batra 1991). In 1991 Batra provided a description of the anamorph, Monilia fructicola Batra 1991, the currently accepted name.

Further confusion was caused by the partial synonyms (syn. pro parte) Sclerotinia cinerea Matheny 1913 and Sclerotinia cinerea (Bonord.) Schröt. ex Aderh. & Ruhland 1905, illegitimate later homonyms of Sclerotinia cinerea (Bonord.) Schröt. 1893 = Monilinia laxa (Aderh. & Ruhland) Honey 1945.

Monilinia laxa;Alternate State (Anamorph): Monilia laxa (Not an APHIS regulated plant pest. Listed for comparison with Monilinia fructigena).

Geographic Distribution: North America (Pacific Northwest), South America, Europe, Asia, Australia, Africa (South Africa).Substrate: Blossoms, shoots, twigs, fruits.Disease Note: The APS common name is brown rot, blossom blight, and fruit rot. Also known as a wilt and canker. Overwinters in mummified fruits.Host Range: Rosaceae, primarily Prunus spp., also Malus spp. (apple), Pyrus spp. (pear), and other Pomoideae.

[Monilia laxa (Wallr.) Sacc. & Voglino 1886 ] invalid name

Note: The teleomorph of this fungus was first described as Sclerotinia laxa by Aderhold & Ruhland in 1905. Chifflot transferred it to Stromatinia (Stromatinia laxa (Aderh. & Ruhland) Chifflot 1921). Honey transferred it to Monilinia as Monilinia laxa (Aderh. & Ruhland) Honey 1945, the currently accepted name.

The nomenclature of the anamorphic state remains controversial (Batra 1991). Ehrenberg’s description of Oidium laxum Ehrenb. 1818 serves as the basionym for the currently accepted name. It is possible, however, that Persoon’s descriptions of Torula fructigena Pers. 1796, Monilia fructigena Pers.:Fr. 1801 and Acrosporium fructigenum (Pers.:Fr.) Pers. 1822 refer to the fungus currently named Monilia laxa rather than to Monilia fructigena (Batra 1991). If this were accepted to be the case, in the genus Monilia the epithet fructigena (1796) would have priority over laxum (1818) for this fungus. The brown fruit rot currently known as Monilia fructigena would also need to be renamed. Because no type specimen is available for Persoon’s fungus, it has been difficult to settle this issue. At this point, M. laxa is the currently accepted name for the conidial state of this fungus (Batra 1991).




Moniliophthora perniciosaNote: Listed by APHIS as Crinipellis perniciosa

Geographic Distribution: South America, Caribbean (Trinidad, Grenada). Also reported in Indonesia (unconfirmed).Substrate: Buds, flowers, fruits.Disease Note: This fungal disease may destroy up to 75% of the crop. The APS common names are currently Crinipellis pod rot and witches’ broom. The APS common names should be updated to reflect the new generic placement, and to prevent confusion with the closely related Moniliophthora pod rot (see Moniliophthora roreri).Host Range: Theobroma spp. including Theobroma cacao (cacao), and Herrania spp. (Malvaceae, also sometimes placed in Sterculiaceae).Fungal Order: Agaricales

Moniliophthora perniciosa (Stahel) Aime & Phillips-Mora 2006 [2005] ≡Marasmius perniciosus Stahel 1915≡Crinipellis perniciosa (Stahel) Singer 1943

Notes: Aime and Philips-Mora (2005) transfered this teleomorphic species to the genus Moniliophthora. The genus Moniliophthora was erected for Moniliophthora roreri, originally considered an anamorphic species. Evans (2002) later argued that Moniliophthora roreri is a teleomorphic name (see discussion under Moniliophthora roreri).

Moniliophthora roreri

Geographic Distribution: Central America (Panama, Cuba), South America.Substrate: Flowers, fruits.Disease Note: The APS common name is Moniliophthora pod rot, also known as frosty pod rot, 'mancha', 'helada', watery pod rot (Fig. 4). Incorrectly referred to as Moniliosis or Monilia disease.

Moniliophthora roreri (Cif.) H.C. Evans, Stalpers, Samson & Benny 1978≡Monilia roreri Cif. 1933 Note: Originally classified as an ascomycete (misapplied).

[Crinipellis roreri (Cif.) H.C. Evans 2002] Note: Invalid name, incomplete citation of basionym (ICBN Art. 33.3).

Notes: This species was originally classified as an ascomycete by Ciferri (1933). Evans et al. (1978) erected the new genus Moniliophthora with this fungus as its type species. According to Evans et al. (1978), no type material is extant; they have designated a neotype (a dried culture of CBS 324.75) (permissable under ICBN Art. 8.4). They originally considered it to be an anamorph; later Evans et al. (2002) argued that what had previously been considered conidiophores and conidia were, in fact, probasidia and metabasidia. Because Ciferri's protologue (1933) contained a description of what may be the teleomorphic state of this fungus, Moniliophthora roreri may be a holomorphic name (ICBN Art. 59.2). The genus Moniliophthora, with M. roreri as type species, may therefore be a holomorphic genus. See also Aime and Phillips-Mora (2005).

Notes: This fungus has received attention under the name Cercospora batatae Zimm. 1904, the name under which it is listed by APHIS as a Regulated Plant Pest in the United States. Cercospora "batatae" is the original spelling; the epithet has been corrected to "batatas".

Chupp (1953) considered Cercospora batatas to be synonymous with Cercospora timorensis Cooke 1883, later transferred by Deighton to the genus Pseudocercospora as Pseudocercospora timorensis (Cooke) Deighton 1976. Pollack (1987), Little (1987) and Crous & Braun (2003) have accepted Chupp’s judgement that Cercospora batatas is a synonym of Pseudocercospora timorensis. Ramularia batatas Racib. 1900 and Cercospora ipomoeae-purpureae J.M. Yen 1965 are also listed by Crous & Braun (2003) as taxonomic synonyms of Pseudocercospora timorensis. The epithet timorensis has priority as the oldest name, therefore the currently accepted scientific name for this fungus is Pseudocercospora timorensis (Cooke) Deighton 1976.

Cercospora ipomoeae-indicae Sawada 1943 is a possible synonym (Chupp 1953).

Pucciniastrum actinidiae Hirats. f. 1936 (anamorphic name in a teleomorphic genus)[= Pucciniastrum actinidiae Hirats. f. ex Hirats. f. 1952 - illegitimate later homonym, teleomorph]

Note: This is an anamorphic name placed in a teleomorphic genus. No legitimate name for the holomorph has currently been published. Hiratsuka (1936) published a description of the uredinial state; the telial state was unknown at the time. In 1952, Hiratsuka added a description of the teleomorphic state to the anamorphic name, thereby creating an illegitimate later homonym (ICBN Art. 59.5 note 1, Art. 59.6 ex. 7).

P.M.D. Martin 1968, which is an invalid name, lacking basionym reference, with no Latin protologue. Hypoxylon necatrix (R. Hartig) P.M.D. Martin is an anamorphic name in a teleomorphic genus (ICBN Art. 59.6).≡Rhizomorpha necatrix R. Hartig 1883 Note: Simultaneous publication of two alternate names based on conidial and rhizomorph morphology (see ICBN Art. 34.2).

= Graphium desmazierii Sacc. 1878 [1879] Note: Original orthography. Mistakenly described by Saccardo as the anamorph of Rosellinia desmazierii (Berk. & Broome) Sacc. 1878 (misapplied, see Petrini 1992). Variant spelling Graphium desmazieri Sacc. 1878

Notes:According to Petrini (1992), the earliest description of the teleomorph of this fungus was provided by Saccardo under the new combination Rosellinia desmazieresii (Berk. & Broome) Sacc. 1878, a misapplication of the basionym Sphaeria desmazierii Berk & Broome 1852. As Saccardo did not explicitly exclude the type of the basionym, the name Rosellinia desmazieresii must refer to the fungus described by Berk. & Broome (Art. 7.4), not to the fungus now referred to as Rosellinia necatrix.

The specific epithet necatrix was first applied to the anamorph of this fungus by Hartig in 1883, who published the name as Rhizomorpha (Dematophora) necatrix. The anamorph was given two alternative names by Hartig (1883), a practice that is permitted by the ICBN (Art. 34.2) in publications previous to 1953. Based on rhizomorph morphology, Hartig (1883) used the name Rhizomorpha necatrix, but parenthetically included Dematophora, apparently as an alternate genus (Hartig 1883, p. 95). On page 125 of the same publication, Hartig argued that the fungus did not fit in any existing conidial genus, and that its unique characters "nöthigt zur Aufstellung einer neuen Gattung, welche Dematophora (Büschelträger) genannt werden mag ...In hinblick....scheint mir der Artname necatrix angemessen zu sein". (translated from the German: "require the establishment of a new genus, which may be named Dematophora...In looking back...the epithet necatrix seems appropriate to me"). As Hartig had originally been careful to include the new alternate genus in the original use of the name, it appears that he intentionally combined the genus Dematophora with necatrix, satisfying Article 33.1, despite the fact that he used the name Rhizomorpha necatrix throughout the rest of the publication. Dematophora necatrix is the type of the genus Dematophora; the two were simultaneously validated (descriptio generico-specifica, Art. 42.1).

Hartig (1883) speculated, based on conidial morphology, that the teleomorph of Dematophora necatrix might belong in Rosellinia or a closely related genus, but was not able to observe production of perithecia to confirm his prediction. Viala (1891) was the first after Saccardo (1878) to observe perithecia, and Berlese (1892) drew upon Viala’s observations to propose that the teleomorph










was a Rosellinia sp. but did not formally propose a name. Prillieux (1902) was the first to publish the name Rosellinia necatrix, originally without attribution of the name to any other authors. In 1904 Prillieux cited the name as Rosellinia necatrix (R. Hart.) Berlese; as a result the name is sometimes cited in the literature as Rosellinia necatrix Berl. ex Prill. 1904, but, based on his original 1902 publication, the name should be Rosellinia necatrix Prill. 1902.

Martin (1968) transferred this fungus to the genus Hypoxylon, providing an English, but no Latin description, of the teleomorph. Because he failed to provide a full citation of the basionym, this name was invalid (ICBN Art. 33.3; Art. 36.1). He later validated the name as Hypoxylon necatrix (R. Hartig) P.M.D. Martin 1976 based on Rhizomorpha necatrix. Because the basionym is an anamorph, and he failed to add a Latin description of the teleomorph, Hypoxylon necatrix must be considered an anamorphic name in a teleomorphic genus (permissible under ICBN Art. 59.6, Ex. 4, 5, 7).

Teleomorphic type material is not extant; Petrini (1992) chose not to designate a neotype because she could not locate a teleomorphic specimen on the original host. After examining perithecia from a collection by Hanson et al. (1937), Francis (1985) suggested that Rosellinia necatrix was synonymous with Rosellinia bothrina (Berk. & Broome) Sacc. 1882, based on the basionym Sphaeria bothrina Berk. & Broome 1873 (see following entry). If this synonymy were accepted, the name Rosellinia bothrina would have priority, however, this has not been adopted by more recent authors (e.g. Petrini 1992, Nakamura et al. 2000).

Based on Saccardo’s 1878 description of the anamorph, Petrini (1992) placed Graphium desmazierii Sacc. 1878 as a synonym of Dematophora necatrix Hartig 1883. Petrini (1992) recommended that the specific epithet necatrix be retained for the anamorph of this fungus rather than the older epithet desmazierii due to the importance of Dematophora necatrix as a pathogen. In anticipation of a proposal to conserve Dematophora necatrix Hartig 1883 against the synonym Graphium desmazierii Sacc. 1878, our nomenclature report retains the name Dematophora necatrix, following Petrini (1992).

Notes: The epithet "areolatum" was sanctioned by Fries; it therefore has priority over the epithet "padi". Uredo padi Kunze & Schmidt 1817 was based on description of the fungus on the telial host (a holomorphic name in an anamorphic genus, see ICBN Art. 59.6, Ex. 4,5,7). Licea strobilina Alb. & Schwein. 1805 was originally classified as a myxomycete, but was based on a description of this fungus on the aecial host. Past authors have asserted that "strobilina", the oldest epithet, should be applied to the holomorph (see Liro 1908), however, this is counter to the current Code (ICBN Art. 59.1).

Notes: Pomatomyces strobilina is the type of the monotypic genus Pomatomyces Oerst. 1864. The genus Pomatomyces is listed as the anamorph of Thekopsora by Kirk et al. (2001) but not included in the list of accepted rust genera by Cummins & Hiratsuka (2003), who describe the aecial state of Thekopsora as Peridermium-type. In the absence of a published combination in Peridermium, we list the aecial state under the accepted name Aecidium strobilinum. Pomatomyces strobilina is based on Licea strobilina, which was originally classified as a myxomycete. In his sanctioning work, Fries transferred it to the myxomycetous genus Perichaena. It was subsequently misapplied to a number of ascomycetous genera by various authors. Reess (1869) recognized that the type specimen contained the aecial state of a rust fungus, and made the transfer to Aecidium.

Cummins 1935 (anamorph)

Cummins (1935) was the first to describe the teleomorphic (telial) state of this fungus. He created the new combination Goplana dioscoreae (Berk. & Broome) Cummins, based on the anamorph, Aecidium dioscoreae Berk. & Broome 1875. Cummins did not provide a Latin description of the teleomorphic state (Art. 36.1), therefore, while a valid name for the anamorph, this cannot serve as a valid name for the teleomorph. Other authors have listed Goplana dioscoreae (Berk. & Broome) Cummins 1935 as an invalid name, nom. nud., because the teleomorph lacked a Latin description (Cummins 1960, Ono 1982, Ono & Hennen 1983). This is contrary to the current Code because the combination was validly published based on the basionym Aecidium dioscoreae Berk. & Broome 1875. Goplana dioscoreae (Berk. & Broome) Cummins 1935 must be considered an anamorph in a teleomorphic genus, typified by A. dioscoreae Berk. & Broome (Art. 59.6, Ex. 7).

In 1960, Cummins republished the name, as Goplana dioscoreae Cummins 1960, non (Berk. & Broome) Cummins 1935, this time providing a Latin description of the teleomorphic state. G. dioscoreae Cummins 1960 non (Berk. & Broome) Cummins 1935 is therefore a validly published name for the teleomorph, but it is an illegitimate later homonym of the anamorphic name Goplana dioscoreae (Berk. & Broome) Cummins 1935 (see Art. 59.6, Ex. 5 and 7). No other legitimate name exists for the teleomorph of Uredo dioscoreae-alatae. A replacement name for G. dioscoreae Cummins 1960 will be proposed in a future publication (Hernandez & Cline, unpublished).

Host Range: Urocystis agropyri sensu stricto is restricted to the grasses Agropyron spp. and Elytrigia spp. Urocystis agropyri in the broader concept of Fischer (1953) includes flag smuts on other grasses, including Triticum spp. (wheat, Poaceae) (see Urocystis tritici).Fungal Order: Urocystales

[Urocystis agropyri-juncei (Vienn.-Bourg.) H. Zogg 1986] Note: Invalid name, no Latin diagnosis (nom. nud.).

Notes: Preuss (1848) published the name Uredo agropyri for a smut occurring on a host plant labelled with the German common name "Quackengras"; authors have interpreted this as the grass currently named Elytrigia repens (as Agropyron repens or Triticum repens). Fischer von Waldheim (1867) transferred this fungus from Uredo to Urocystis, citing as basionym Uredo agropyri Pers.; however, there is no record that Persoon ever published this name. Körnicke (1877) speculated that the author attribution was the result of a typographical error. The incorrect author citation does not invalidate the name (ICBN Art. 33.4), and it should be cited as Urocystis agropyri (Preuss) A.A. Fisch. Waldh. 1867.When making the new combination Urocystis agropyri, Fischer von Waldheim (1867) added a description of a smut on the host Carex acuta (Cyperaceae); however, this smut is now considered to be a distinct species, Urocystis fischeri Körn. ex G. Winter 1881. Despite being applied by Fischer von Waldheim to the smut of Carex, the name Urocystis agropyri refers to the flag smut of Poaceae, typified by the type of its basionym, Uredo agropyri (ICBN Art. 7.4).

Schröter (1869) described Urocystis agropyri, listing Triticum repens (≡Elytrigia repens) as host. Körnicke (1877) argued that the name Urocystis agropyri (Preuss) A.A. Fisch. Waldh. 1867 should be rejected because the description refers to a different fungus than the basionym cited, and instead the name Urocystis agropyri (Preuss) J. Schröt. 1869 should be the accepted name for the flag smut of Poaceae, but this is counter to the current Code (ICBN Art. 7.4). The name is commonly erroneously cited as Urocystis agropyri (Preuss) J. Schröt. 1869 in the literature.

Körnicke (1877) suggested that the smut described by Fischer von Waldheim on Carex acuta under the name Urocystis agropyri be named Urocystis fischeri, retaining the name Urocystis agropyri for the flag smut of Poaceae. He failed to provide a description, therefore, it fell to Winter (1881) to provide a description and validate the name, as Urocystis fischeri Körn. ex G. Winter 1881.

Using a morphological species concept, Fischer (1953) rejected species distinctions based on host specificity within the Poaceae and treated an extensive list of Urocystis species, including Urocystis tritici, as synonyms of Urocystis agropyri. This has not been accepted by most later authors (Purdy 1965, Scholz 1988, Vanky 1994, Denchev 2001, but see Mordue & Ainsworth 1984).

Notes: Körnicke assigned the new name Urocystis fischeri to the fungus described by Fischer von Waldheim on Carex acuta under the name Urocystis agropyri. Because he did not provide a description, this is an invalid name (nom. nud.). Winter later provided a description and validated the name Urocystis fischeri Körn. ex G. Winter 1881. The invalid name Urocystis caricis Ule 1884 (nom. nud., no description) has also been applied to this fungus.
