New teleomorph combinations in the entomopathogenic genus Metacordyceps

The genus Metacordyceps contains arthropod pathogens in Clavicipitaceae (Hypocreales) that formerly were classified in Cordyceps sensu Kobayasi et Mains. Of the current arthropod pathogenic genera of Hypocreales, the genus Metacordyceps remains one of the most poorly understood and contains a number of teleomorphic morphologies convergent with species of Cordyceps s.s. (Cordycipitaceae) and Ophiocordyceps (Ophiocordycipitaceae). Of note, the anamorph genera Metarhizium and Pochonia were found to be associated only with Metacordyceps and demonstrated to be phylogenetically informative for the clade. Several species of Cordyceps considered to have uncertain placements (incertae sedis) in the current taxonomic framework of clavicipitoid fungi were collected during field expeditions mostly in eastern Asia. Species reclassified here in Metacordyceps include Cordyceps atrovirens Kobayasi & Shimizu, Cordyceps indigotica Kobayasi & Shimizu, Cordyceps khaoyaiensis Hywel-Jones, Cordyceps kusanagiensis Kobayasi & Shimizu, Cordyceps martialis Speg., Ophiocordyceps owariensis Kobayasi, Cordyceps pseudoatrovirens Kobayasi & Shimizu and Ophicordyceps owariensis f. viridescens (Uchiy. & Udagawa) G.H. Sung, J.M. Sung, Hywel-Jones & Spatafora. Incorporation of these species in a multigene phylogenetic framework of the major clades of clavicipitoid fungi more than doubled the number of species in Metacordyceps and allowed for refinement of morphological concepts for the genus consistent with the phylogenetic structure. Based on these findings we then discuss evolution of this genus, subgeneric relationships, anamorph connections, and suggest additional species that should be confirmed for possible inclusion in Metacordyceps.     

刺枝野丁香和穗花野丁香(茜草科)名称之合格发表

刺枝野丁香Leptodermis pilosa Diels var．acanthoclada Lo和穗花野丁香L．pilosa Diels vat．spicatiformis Lo发表时没指明模式,是不合格发表的名称。现通过指定模式,将它们的名称作合格发表。还对此2新变种及其近缘类群提供了分类检索表和地理分布图。     

Validation of names of Leptodermis pilosa var. acanthoclada and L. pilosa var. spicatiformis (Rubiaceae)

The names of Leptodermis pilosa Diels var. acanthoclada Lo and L. pilosa Diels var. spicatiformis Lo are invalid because no type specimens were indicated in the protologue when they were published. Two names are here validated at the rank of variety, with the specimens designated as types. A key to varieties in Leptodermis pilosa Diels and a distribution map of two new varieties and their relatives are provided.     

冬虫夏草无性型研究概况*

文献调查结果表明与冬虫夏草有关的无性型菌种已报道有22个学名,涉及13个属。针对这些名称上存在的命名问题本文展开了讨论,并评述了不同名称与冬虫夏草的关系及其有关菌种的研究进展。在已报道的分离菌种中,作为新种正式描述的名称有8个,其中6个为合格发表,其余2个未能满足名称合格发表的条件;还有4个名称在文献中作为新种提到,但没有合格发表的出处,也有一例只提到名称而无其他要素;另有5个名称则只有属名,尚未鉴定到种的水平。中国被毛孢为多个独立的研究证明为冬虫夏草的无性型,还有3个无性型名称已被证明不可能是冬虫夏草的无性型。其他无性型名称与冬虫夏草的关系有待进一步验证。文中对与冬虫夏草有关的菌种定名、无性型分离和验证方法、复无性型现象,以及有关学名问题作了讨论。     

Reassessment of type specimens of Cordyceps and its allies described by Dr. Yosio Kobayasi, preserved in the National Museum of Nature and Science. Part 2: Cordyceps (Elaphocordyceps) on Elaphomyces

Four holotype specimens of Cordyceps parasitic on Elaphomyces that were originally described by Dr. Yosio Kobayasi and Mr. Daisuke Shimizu were relocated, and TNS (National Museum of Nature and Science, Japan) registration numbers (TNS-F-number) were assigned: viz. Cordyceps minazukiensis (TNS-F-197989), C. ophioglossoides var. cuboides (TNS-F-230312), C. valvatistipitata (TNS-F-230284), and Cordyceps × jezoensoides (TNS-F-230286). Two specimens were selected as lectotypes: C. delicatistipitata (TNS-F-230293) and C. ophioglossoides f. alba (TNS-F-18223). Those taxa, except for Cordyceps × jezoensoides, have been treated as members of the genus Elaphocordyceps in the latest taxonomy. The new combination Elaphocordyceps × jezoënsoides (Kobayasi) is proposed. In addition, Elaphomyces asahimontanus Kobayasi, the host of Cordyceps delicatistipitata, is lectotypified (TNS-F-230293).     

Reassessment of type specimens of Cordyceps and its allies, described by Dr. Yosio Kobayasi and preserved in the mycological herbarium of the National Museum of Nature and Science (TNS). Part 3: Cordyceps s. l. on Cicadidae

Twenty taxa of Cordyceps s. l. (belonging to three genera in the latest taxonomic system) from Cicadidae had been described by Kobayasi and Shimizu. Among them, 13 holotype specimens of Cordyceps were rediscovered from preserved specimens partially without ordering, and their registration numbers (TNS-F-number) were given: viz. (1) Elaphocordyceps inegoensis TNS-F-230289, (2) Elaphocordyceps paradoxa TNS-F-230313, (3) Elaphocordyceps toriharamontana TNS-F-230288, (4) Ophiocordyceps heteropoda TNS-F-230294, (5) Ophiocordyceps longissima TNS-F-230285, (6) Ophiocordyceps prolifica f. terminalis TNS-F-230295, (7) Ophiocordyceps pseudolongissima TNS-F-197983, (8) Ophiocordyceps takaoensis TNS-F-3026, (9) Cordyceps kanzashiana TNS-F-198015, (10) Cordyceps kobayasii Koval’ (≡C. sinclairii Kobayasi, not C. sinclairii Berk.) TNS-F-212384, (11) Cordyceps minuta TNS-F-11933, (12) Cordyceps ramosopulvinata TNS-F-197979, and (13) Cordyceps ryogamimontana TNS-F-230292. Two specimens were selected as lectotype: viz. (14) Ophiocordyceps prolifica TNS-F-230300 and (15) Ophiocordyceps yakusimensis TNS-F-230287. A paratype specimen of (16) Cordyceps pleuricapitata TNS-F-197965, and an authentic specimen of (17) Cordyceps imagamiana TNS-F-197966, were also rediscovered.     

Notes on Echinodorus (Alismataceae)

Errors by Rataj in lecto- and neotypification of five names inEchinodorus are corrected. These errors include the selection of lectotype specimens that were not cited in the protologue and the designation of neotypes from syntypes. Lectotypes for four of the names are designated here. The other is not typified at this time, as we have as yet been unable to examine the cited collections. In addition, a lectotype is designated for the Linnaean nameAlisma cordifolia, a name for which Rataj did not choose a lectotype. A new species,Echinodorus reticulatus, is described and illustrated. Five new combinations at the subspecies level are proposed, with most of these subspecies having a distribution from Central America to Paraguay and Argentina.     

Valid publication of the name Helicia falcata (Proteaceae)

Helicia falcata C. Y. Wu was not validly published in 1977 because two gatherings, one flowering and one fruiting, were simultaneously designated as types in the protologue. This name is validated here by designating the flowering specimen as the holotype.
