... Although sequence data of some species, such as P. effusa, P. metepisphaeria (Samuels) C.S. Herrera & P. Chaverri, P. nummulariae, P. pithoides (Ellis & Everh.) C.S. Herrera & P. Chaverri, P. pseudepisphaeria (Samuels) C.S. Herrera & P. Chaverri and P. triqua are not available, P. shennongjiana and P. curvispora can be easily distinguished from them by sizes of perithecia, asci, and ascospores (Samuels et al. 1991;Zhuang and Zhang 2002;Herrera et al. 2013). ...
... Some Pseudocosmospora spp. favor Diatrypaceae, especially Eutypa and Eutypella, with the exceptions of P. joca and P. nummulariae commonly found on Xylariaceae, and P. hypoxylicola Lechat & J. Fourn on Hypoxylaceae (Zhuang and Zhang 2002;Herrera et al. 2013;Lechat and Fournier 2020). Many fungal hosts of Pseudocosmospora are hardly identified to species due to their decayed condition. ...
... Pseudocosmospora is worldwide distributed and expects to show high species diversity in warm temperate and tropical regions (Herrera et al. 2013). Among them, P. effuse, P. hypoxylicola, P. metajoca, P. metepisphaeria, P. nummulariae, P. pithoides, P. pseudepisphaeria, and P. rogersonii are probably rare species and only known from their type locations (Zhuang and Zhang 2002;Herrera et al. 2013;Lechat and Fournier 2020). Since P. nummulariae was first reported in the 1930s, additional taxa of the genus were successively discovered from different regions of China. ...

To explore species diversity of the genus Pseudocosmospora, collections from Beijing and Hubei Province of China were examined, and three undescribed species were encountered. Morphological features and DNA sequence analyses of the ITS, nc LSU rDNA, RPB1, and TUB regions support their placement in Pseudocosmospora and recognition of two new species. Pseudocosmospora curvispora sp. nov. encountered on fruiting bodies of a species of the Diatrypaceae has gregarious, subglobose to obpyriform perithecia seated directly on the host fungus clavate asci, with eight ellipsoidal, smooth ascospores, acremonium- to verticillium-like conidiophores, and strongly curved, allantoid, unicellular conidia. Pseudocosmospora shennongjiana sp. nov. is characterized by solitary to gregarious, subglobose to globose perithecia with a minute basal stroma clavate asci, containing eight ellipsoidal, spinulose ascospores, acremonium-like conidiophores, and rod-shaped, unicellular conidia. An unnamed species of the genus is also described. Distinctions between these species and their close relatives are compared in detail. The previously recorded species of the genus in China are briefly reviewed.
... They are characterized by small-sized perithecia with glabrous surface or with few to numerous hairs arising from the wall surface, having adjacent perithecial wall cells joined by fine pores, consisting of parallel hyphal elements in papilla, and connected with several anamorphic genera (Rossman et al., 1999). Fifty-six species of the genus are currently accepted, and 15 have been reported from China (Rossman et al., 1999;Fröhlich and Hyde, 2000;Samuels and Nirenberg, 2000;Zhuang and Zhang, 2002;Hosoya and Tubaki, 2004;Nong and Zhuang, 2005). ...
... The results indicate that the two new species of Cosmospora are close-related and that Cosmospora as currently defined is not monophyletic. This work is a continuation of our taxonomic studies on nectriaceous fungi from China (Zhuang, 2000;Zhuang and Zhang, undertaken. For anatomic study, longitudinal sections through ascomata were made with a freezing microtome (YD-1508-III, Yidi Medical Appliance Factory, Jinhua, Zhejiang) at a thickness of ca 10 µm. ...

Two new species, Cosmospora gigas and C. cupularis, and their anamorphs are described and illustrated. Their morphological affinities to related taxa are discussed. Phylogenetic relationships of the two new species with some fungi of the Nectriaceae are revealed based on analyses of the ITS1-5.8S-ITS2 and 28S rDNA partial sequences. The results indicate their taxonomic position in Cosmospora, a genus that as currently defined, is not monophyletic.
... Combining molecular data with morphological evidences, Gräfenhan et al. (2011) restricted Cosmospora in a much narrower sense to include only the species growing on polypores and xylariaceous fungi and having acremonium-like or verticillium-like asexual states. About 19 species are currently accepted in the genus (Zhuang and Zhang 2002;Gräfenhan et al. 2011;Herrera et al. 2015). The remaining cosmospora-like fungi were transferred to Chaetopsina Rambelli, Cylindrocladiella Boesew., Dialonectria, Fusicolla Bonord., Macroconia (Wollenw.) ...
... Studies on Cosmospora in China were initiated by Teng (1934) who discovered C. ustulinae (Teng) C. Herrera & P. Chaverri (as Nectria ustulinae Teng), and first reported from Jiangsu Province. Cosmospora damingshanica W.Y. Zhuang & X.M. Zhang from Guangxi Province (Zhuang and Zhang 2002) was later added. In connection with our current study on the Chinese fungus flora, especially on Nectriaceae, two fungicolous species from northeast China were encountered. ...

A new fungicolous species, Cosmospora inonoticola, is described and illustrated based on a specimen collected from northeast China. It is characterized by the occurrence of fruitbodies of Inonotus sp.; perithecia nonstromatic, subglobose to pyriform, not collapsing when dry; clavate asci containing (3–)6(−8) spores; ascospores ellipsoidal to broadly ellipsoidal, pale brown, finely warted, bicellular, conspicuously constricted at septum; and producing a verticillium-like asexual state. A multi-locus analysis of the combined ITS, rpb1 and tub sequences confirmed its taxonomic position, and revealed the distinction from its morphologically similar species including the type species, C. coccinea, which occurs also on Inonotus. A specimen with sexual state of C. lavitskiae is reported for the first time, and a reference specimen is indicated.

Nectria berberidis sp. nov. and Thyronectria berberidicola sp. nov. isolated from Berberis heteropoda in Xinjiang Uygur Autonomous Region, China, are described and illustrated. Nectria berberidis is characterized by clavate asci (50–87 × 8–12 μm) with ellipsoidal to fusiform, 1-septate ascospores. Thyronectria berberidicola is characterized by clavate asci (117–25.9 × 63.7–117.9 μm) with ellipsoidal to fusiform ascospores that have 5–8 transverse septa and 1(–2) longitudinal septum. Ascospores bud to produce hyaline, bacillar ascoconidia. Phylogenetic analyses based on alpha-actin (ACT), the internal transcribed spacer (ITS), the large nuclear ribosomal RNA subunit (LSU), translation elongation factor 1-alpha (TEF1) and the β-tubulin (TUB) sequence data revealed that isolates of N. berberidis and T. berberidicola form a distinct clade within Nectria and Thyronectria, respectively. In addition, Nectria nigrescens is reported for the first time in China.
... SAmueLS (1985) established the connection between some Chaetopsina asexual morphs with the sexual morphs of four new hypocrealean species assigned to the Nectria episphaeria group in the broad sense, based on similar peridial anatomy. the sexual morphs associated with Chaetopsina asexual morphs were thereafter placed in Cosmospora (roSSmAn et al., 1999;nirenBerG & SAmueLS, 2000;ZhuAnG & ZhAnG, 2002;hoSoYA & tuBAKi, 2004;nonG & ZhuAnG, 2005;hirooKA et al., 2008;roSSmAn et al., 2008).

A new species, Sarcopodium tibetense, is described on rotten stem base of maize straw from the Tibet Autonomous Region. The anatomy of perithecia, which covered with septate, curved hairs on the surface, striate ascospores, and penicillate conidiophores indicate that the fungus belongs to Sarcopodium. It is characterized by solitary to gregarious perithecia that are globose to subglobose or pyriform, not becoming cupulate upon drying, and with hyaline hairs on surface; cylindrical to clavate asci with eight ascospores that are fusiform to ellipsoidal and striate. The asexual state is penicillium-like and with subglobose, ellipsoidal, oblong to rod-shaped, aseptate, smooth, hyaline conidia aggregated in a slimy mass. Sarcopodium tibetense is distinguished from its morphologically similar species, S. circinosetiferum, by narrower conidiophores and the presence of 50 bp and 9 bp sequence divergences in the ITS and LSU regions. Sequence analysis of the combined act, ITS, LSU and tub genes confirm its taxonomic position in Sarcopodium as a species new to science.

Genus Chaetopsinectria is established to accommodate four species, previously assigned to Cosmospora, that possess Chaetopsina anamorphs, small and red perithecia not collapsing when dry, a typical Cosmospora perithecial wall structure, clavate asci, smooth or striate ascospores, sienna colonies on PDA, and on decaying debris or woody substrates. The segregation of the new genus from Cosmospora is well supported by sequence analyses of nuclear ribosomal DNA (ITS and 28S partial) with maximum parsimony and Bayesian methods. The molecular data indicate that the new genus is distantly related to Cosmospora coccinea Rabenh., the type species of Cosmospora sensu stricto, and its related fungi. Four new combinations, Chaetopsinectria chaetopsinae, C. chaetopsinae-catenulatae, C. chaetopsinae-penicillatae and C. chaetopsinae-polyblastiae, are proposed.

The holomorphic genus Bionectria, with anamorphs classified in Clonostachys, is characterized and compared to related taxa of the Hypocreales. Bionectria species form penicillate, solitary or sporodochial conidiophores and imbricately arranged conidia held in chains or columns that may collapse into slimy masses. The superficially free ascomata often occur on other fungi, mainly ascomycetes, on bark of recently dead trees, or on decaying leaves. Anamorphs of Bionectria species, such as Clonostachys rosea (= Gliocladlium roseum), are often encountered in soil and are known as destructive mycoparasites. Based mainly on characters of the teleomorph, such as occurrence of a supporting stroma, the interface between the stroma and the perithecial wall, anatomy of the perithecial wall, ascospore morphology, habit on and type of the natural substratum, six infrageneric subgroups are distinguished. Characters of the anamorph, such as the tendency to form dimorphic conidiophores and/or sporodochia, occurrence of intercalary phialides or setae, conidial shape, and pigmentation of conidial masses, partly support the subgroups delimited using teleomorph characters, but all subgroups can be linked with each other by intermediate patterns of anamorphs. Based on the general occurrence of penicillate conidiophores and suspected similarities in their life-styles, classification of all species in one genus is suggested. To address differences found in the anamorphs, the terms dendrodochium-, sesquicillium-, myrothecium-, and gliocladium-like are used. Analyses of rDNA sequences suggest monophyly of all taxa considered, while certain phenotypic characters appear in paraphyletic positions.

The Hypocreales with over one thousand described species have been the repository for all light- to bright-colored, soft-textured, perithecial ascomycetes with a Nectria-type centrum. Rogerson (1970) published a key to the genera in the Hypocreales and accepted over 115 genera with 26 generic synonyms in the order. Since then, 58 genera have been added. For this study all available type specimens of the type species of genera classified in the Hypocreales were examined. Fifty six genera, including six newly described genera with 43 generic synonyms, are accepted in three families, Bionectriaceae fam, nov., Hypocreaceae and Nectriaceae, of the order. Although now considered either part of or closely related to the Hypocreales, neither the Niessliaceae nor the Clavicipitaceae are treated comprehensively in this study. Fourteen genera with two generic synonyms are included in the Niessliaceae and six genera with one generic synonym are placed in the Clavicipitaceae. The remaining 84 genera are excluded from the Hypocreales and redisposed in their appropriate family and order. Genera excluded from the Bionectriaceae, Hypocreaceae, and Nectriaceae are described and illustrated based on their type species. For 16 genera previously placed in the Hypocreales the type specimen was either not located or not sufficient to make a modern taxonomic evaluation of the type species. For each genus the type species and species not recently treated are fully described and documented. A key to species is presented unless a recent key to species in that genus is available. In the Bionectriaceae a new genus, Ochronectria, is introduced for Nectria calami. Nectriella minuta, N. rubricapitula, N. utahensis, Pronectria echinulata, P. pertusariicola, and Protocreopsis viridis are described as new species. The following new specific combinations are proposed: Dimerosporiella cephalosporii, D. gnarapiensis, D. leucorrhodina, D. oidioides, D. pipericola, and D. sensitiva; Hydropisphaera arenula, H. arenuloides, H. boothii, H. cyatheae, H. dolichospora, H. erubescens, H. gigantea, H. haematites, H. hypoxantha, H. leucotricha, H. macrarenula, H. multiloculata, H. multiseptata, H. nymaniana, H. pachyderma, and H. suffulta; Ijuhya peristomialis, I. chilensis, I. aquifolii, I. bambusina, I. corynespora, I. dentifera, I. dictyospora, I. leucocarpa, I. paraparilis, and I. parilis; Lasionectria sylvana and L. vulpina; Nectriella curtisii, N. dakotensis, and N. galii; Nectriopsis sasae and N. queletii; Ochronectria calami; Peethambara spirostriata and for its anamorph Didymostilbe echinofibrosa, Protocreopsis foliicola, P. freycinetiae, P. javanica, P. pertusa, P. pertusoides, and P. phormiicola; Stilbocrea gracilipes and S. impressa. Two new names, Nectriella crouanii for Nectria aurea P. & H. Crouan, and N. halonata for Charonectria umbelliferarum, are proposed. In the Nectriaceae five new genera are introduced: Albonectria for species related with Nectria rigidiuscula, Haematonectria for the Nectria haematococca complex, Lanatonectria for the Nectria flavolanata-group, Rubrinectria for a species previously known as Nectria olivacea, and Viridispora for teleomorphs of Penicillifer. Cosmospora dingleyae and C. obscura are described as new species. The following new specific combinations are proposed: Albonectria rigidiuscula, A. albosuccinea, and A. verrucosa; Corallomycetella repens and C. jatrophae; Cosmospora aurantiicola, C. biasolettiana, C. camelliae, C. chaetopsinae, C. chaetopsinae-catenulatae, C. chaetopsinae-penicillatae, C. chaetopsinae-polyblastiae, C. chlorina, C. consors, C. digitalicola, C. diminuta, C. diploa, C. episphaeria, C. flammea, C. flavoviridis, C. ganymede, C. geastroides, C. glabra, C. joca, C. jucundula, C. kurdica, C. lasiodiplodiae, C. leptosphaeriae, C. macrochaetopsinae, C. magnusiana, C. meliopsicola, C. metepisphaeria, C. nothepisphaeria, C. papilionacearum, C. peponum, C. pseudepisphaeria, C. pseudoflavoviridis, C. purtonii, C. rickii, C. rishbethii, C. rubrisetosa, C. sansevieriae, C. stilbellae, C. stilbosporae, C. thujana, C. triqua, C. tungurahuana, C. vilior, C. viliuscula, C. wegeliana, and C. xanthostroma; Haematonectria haematococca, H. illudens, H. ipomoeae, H. monilifera, and H. termitum; Lanatonectria flocculenta with anamorph Actinostilbe macalpinei, L. flavolanata, L. mammiformis with anamorph Actinostilbe mammiformis, and L. raripila; Neonectria coccinea and N. galligena; Rubrinectria olivacea; Viridispora penicilliferi, V. alata, V. diparietispora, and V. fragariae; Xenonectriella leptaleae, X. ornamentata, and X. streimannii. In the checklist, some genera are excluded from the families treated here and placed among 19 families in 12 orders of ascomycetes and one basidiomycetous genus. Two genera are uniloculate, discomycetous loculoascomycetes; some have true apothecia and belong in the Helotiales and Pezizales, or are lichenized Lecanorales. Many of these taxa are placed in the Diaporthales and Xylariales (Hyponectriaceae and Thyridiaceae). Genera having immersed ascomata are often difficult to place; they include Charonectria and Hyponectria, now placed in the Hyponectriaceae, Xylariales; and Cryptoleptosphaeria, Cryptonectriella and Schizoparme, now placed in the Diaporthales. Several genera are placed in the Niessliaceae and Clavicipitaceae of the Hypocreales. In this section a new species, Charonectria amabilis, is described, and the new combinations Thyridium ohiense, Charonectria sceptri, Cryptoleptosphaeria gracilis, Cryptonectriella geoglossi, and Thelocarpon citrum, are proposed.

(1999) but it was not found on the substratum of the Hong Kong collection. This is a new record for China. Nectria lateritia (P. Karst.) Rossman, Mycol. Pap. 150: 22, 1983 SPECIMEN EXAMINED: China.
