摘　　要：锥盖伞属Conocybe和小鳞伞属Pholiotina界限不明确,在分类上存在混乱。本研究基于中国材料,明确该2属分类学特征,并探索属下等级划分:确认我国锥盖伞属37种,其中白色组sect.Candidae 3种;赭小皮伞组sect.Ochromarasmius 1种;具毛组sect.Pilosellae 10种,含3个中国新记录种,即毛柄锥盖伞Conocybe velutipes、条斑锥盖伞C.moseri和双孢锥盖伞C.bisporigera;锥盖伞组sect.Conocybe 17种,含2个中国新记录种,即刺毛锥盖伞C.echinata、短柄锥盖伞C.brachypodii;混杂组sect.Mixtae 6种。小鳞伞属18种,其中疣孢组sect.Verrucisporae 2种,其中糙孢小鳞伞Pholiotina dasypus为中国新记录;过渡组sect.Intermediae 2种;小鳞伞组sect.Pholiotina 6种;被外菌幕组sect.Vestitae 3种,齿缘小鳞伞Ph.serrata(T.Bau&J.Liu)T.Bau et H.B.Song为新组合;蓝色组sect.Cyanopodae 2种,其中蓝柄小鳞伞Ph.cyanopus为中国新记录种;被毛组sect.Piliferae 3种,其中喜粪小鳞伞Ph.coprophila为中国新记录种。编制了我国锥盖伞属和小鳞伞属的分属及属下分组、分种检索表,对新记录种进行形态学描述及绘制线条图,并采用最大似然法和贝叶斯分析法基于ITS1、5.8S和ITS2序列构建了系统发育树,旨在探明该2属与其他相关类群之间可能的系统发育关系。The delimitation between Conocybe and Pholiotina was ambiguous and controversial.Based on examination of specimens and literature,the taxonomic characteristics of these two genera were illustrated and explor their subgeneric classification was defined.At present,there are 37 species of Conocybe and 18 species of Pholiotina in China.In the Conocybe,there are 3 species of sect.Candidae,1 of sect.Ochromarasmius,10 of sect.Pilosellae,17 of sect.Conocybe and 6 of sect.Mixtae.Among them,sect.Pilosellae harbors 3 new Chinese records,namely Conocybe velutipes,C.moseri and C.bisporigera;sect.Conocybe contains 2 new Chinese records,namely C.echinata and C.brachypodii.In the Pholiotina,there are 2 species of sect.Verrucisporae,2 of sect.Intermediae,6 of sect.Pholiotina,3 of sect.Vestitae,2 of sect.Cyanopodae and 3 of sect.Piliferae.Among them,Pholiotina dasypus was a new Chinese record in sect.Verrucisporae.Ph.serrata was proposed as a new combination in sect.Vestitae.Ph.cyanopus is a new Chinese record in sect.Cyanopodae,and Ph.coprophila was a new Chinese record in sect.Piliferae.Keys to the sections and species of Conocybe and Pholiotina from China are compiled,and the morphological descriptions and line drawings of newly recorded species are provided.Phylogenetic trees based on ITS1,5.8S and ITS2 sequences are used to show the possible evolutionary relationships among the fungal taxa.
