摘　　要：本研究报道了丝膜菌属的一个新种:李玉丝膜菌,该种采自中国吉林省蒙古栎林中,其主要特征为担子体小型、幼时具蓝紫色调,菌盖强水浸状、具条纹,担孢子近球形。该种在系统发育树中形成一个独立的分支,与斑丝膜菌组形成姐妹关系,但遗传关系较远,属于新组李玉丝膜菌组。本文对新分类单元进行了详细描述,并对其系统发育上相近的物种进行了比较。A telamonioid species new to science,Cortinarius liyui,found from Jilin Province,Northeast China is presented based on morphological characteristics and molecular phylogenetic analysis.The species is characterized by its small and violet tinged basidiomata,hygrophanous and striate pileus,and subglobose to broadly ellipsoid basidiospores.The phylogeny inferred from the ITS and 28S sequences demonstrates that C.liyui belongs to Cortinarius sect.Liyuorum,a section new to science and probably related to sect.Spilomei.Detailed descriptions of the new taxon and a comparison with its phylogenetically related taxa are provided.
