丝膜菌属的分类研究进展

Research Progress on the Taxonomy of Cortinarius(Agaricales,Cortinariaceae)

丝膜菌属[Cortinarius(Pers.)Gray]是在全球森林生态系统中广泛分布的外生菌根真菌,物种多样性丰富,具有较高的经济价值和研究价值。主要从丝膜菌属的生态和经济价值,资源和分类学,分子系统学等方面对近年来的研究进展进行综述。丝膜菌属的分类研究存在的主要问题是用以划分种类的形态学标准不一致,分子系统学的研究只涉及少数的基因片段,属以下的分类单元界限不清、分类混乱,现有数据库无法帮助人们准确识别物种,解决以上问题是今后丝膜菌属分类研究的主要方向。

Cortinarius(Pers.)Gray is the most diverse and species-rich genus of ectomycorrhizal fungi widely distributed in global forest ecosystem.It has high economic value and research value.This article summarizes the research progress in recent years from the ecological and economic value,resources,classical taxonomy,molecular phylogenetic of the genus.The main problem in the taxonomy of Cortinarius is that the morphological criteria used to classify species were not consistent.The research of molecular phylogeny only involved a few gene fragments,infrageneric taxa were unclear and the classification was chaotic.The existing database can’t help people to identify species accurately.The future researches will focus on these issues.
