摘　　要：The chalara-like anamorphs of Leotiomycetes are phialidic hyphomycetes with cylindrical collarettes and deeply seated sporulating loci,and hyaline,aseptate or septate,cylindrical conidia.They are commonly found on plant litters in both terrestrial and submerged environments,and with broad geographical distribution.This paper reports our research result of diversity,taxonomy and phylogeny of these fungi in China,which is based on a systematic study by using an integrated approach of literature study,morphological observation and phylogenetic analyses of 153 chalara-like fungal species with diversified morphology in conidiomata,setae,conidiophores,phialides and conidia.The phylogenetic analyses employing different datasets of SSU,LSU and ITS sequences of 116 species showed that these chalara-like fungi were paraphyletic and scattered in 20 accepted genera belonging to five families of Leotiomycetes:Arachnopezizaceae,Hamatocanthoscy-phaceae,Helotiaceae,Neolauriomycetaceae and Pezizellaceae.Additional six genera,Ascoconidium,Bioscypha,Chalaro-dendron,Didonia,Phaeoscypha and Tapesina,all reported with chalara-like anamorphs in literatures,are also accepted as members of Pezizellaceae or Leotiomycetes genera incertae sedis.Among of these 26 accepted genera of chalara-like fungi in Leotiomycetes,17 genera are asexually typified genera(Ascoconidium,Bloxamia,Chalara,Chalarodendron,Constric-tochalara,Cylindrochalara,Cylindrocephalum,Leochalara,Lareunionomyces,Minichalara,Neochalara,Neolauriomyces,Nagrajchalara,Parachalara,Stipitochalara,Xenochalara and Zymochalara),and 9 are sexually typified genera(Bioscypha,Bloxamiella,Calycellina,Calycina,Didonia,Hymenoscyphus,Mollisina,Phaeoscypha and Tapesina).The phylogenetic significance of conidial septation in generic delimitation was further confirmed;while other morphologies such as conidi-omata,setae,conidiophores,phialides,conidial length,and conidial ornamentation have little phylogenetic significance,but could be used for species delimitation.The polyphyletic genus Chalara s
