在形态学研究和分子系统发育分析的基础上,本文报道了丝盖伞属丝盖伞亚属3个中国新记录种,分别为垂暮丝盖伞Inocybe appendiculata、薄囊丝盖伞I.leptocystis和华美丝盖伞I.splendens。根据国内采集的材料对此3种进行了描述和绘图。通过对馆藏标本的查阅给出了它们已知的国内地理分布。对丝盖伞亚属国内已证实有分布的28个分类群编制了分种检索表。
Three newly recorded species, Inocybe appendiculata, I. leptocystis and I. splendens, are documented based on morphological and molecular phylogeny. They belong to Inocybe subg. Inocybe. A detailed description and line drawing are given for each species. Their provincial distributions in China are given based on the examination of herbarium materials. A key to 28 currently verified taxa in I. subg. Inocybe in China is provided.
