中国丝膜菌属特拉蒙组(蘑菇目)的两个新种
Two new species of Cortinarius sect.Telamonia(Agaricales)from China
摘要
Abstract
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.关键词
