中国丝膜菌属特拉蒙组(蘑菇目)的两个新种OA
Two new species of Cortinarius sect.Telamonia(Agaricales)from China
特拉蒙亚属subgen.Telamonia是狭义丝膜菌属Cortinarius中最大的亚属.该亚属展现出极高的物种多样性,被认为是狭义丝膜菌属中分类学最具挑战性的类群之一.在中国,特拉蒙亚属的物种约占已知狭义丝膜菌属物种的40%.然而,其物种多样性很可能仍被严重低估.本研究基于形态学证据和分子系统发育分析,描述了采自中国西南部的 2 个新物种:变暗丝膜菌C.obscuratus和高山丝膜菌C.alpigenus,二者均归属于该亚属下的特拉蒙组 sect.Telamonia.变暗丝膜菌分布于云南的亚热带地区,主要见于高黎贡山;而高山丝膜菌仅发现于温带亚高山生境.本文为 2 个新物种提供了详细形态描述、生境照片及线条图,并与其相近物种进行了比较讨论.
The subgen.Telamonia(Fr.)Trog is the largest subgenus in the genus Cortinarius sensu stricto.This subgenus shows exceptionally high species diversity and is considered as the most taxonomically challenging groups in Cortinarius s.str.In China,species belonging to the subgen.Telamonia represent about 40%of the known Cortinarius s.str.species,however,the species diversity of the subgenus in China probably remains largely underestimated.Here,based on morphological evidence and molecular phylogenetic analyses,two new species within the subgenus from southwestern China are described,namely C.obscuratus and C.alpigenus.Cortinarius obscuratus occurs in subtropical regions of Yunnan,primarily in the Gaoligong Mountains,whereas C.alpigenus is exclusively found from temperate subalpine habitats.Detailed descriptions,habitat photographs,and line drawings are provided,and a comparative discussion of their allied species are given.
