采自东北的中国滑锈伞属新记录种

摘要

在对采自内蒙古自治区和吉林省的滑锈伞属Hebeloma标本研究中,发现3个中国新记录种:高山滑锈伞H.alpinum、沙地滑锈伞H.dunense和白缘滑锈伞H.leucosarx.本文提供了这3个种的形态特征描述、显微结构线条图、担孢子电镜照片以及ITS序列.根据ITS核苷酸序列进行的分子系统发育分析支持形态分类结果.%During making a survey of Hebeloma collections from Inner Mongolia Autonomous Region and Jilin Province,three species,namely H.alpinum,H.dunense and H.leucosarx,were found to be unrecorded previously in China.Morphological characters of the three species were described,together with line drawings,SEM images of spores,and ITS sequence for each species.Phylogenetic analysis based on ITS nucleotide sequences supported our morphology-based taxonomy.
