had accommodated only two species for more than half a century and as many as 17 new species have been described in this genus since 2015. However, no systematic studies were conducted for this genus so far. The distribution, substrate and morphology of all known species in are analysed herein. Meanwhile, with the support of phylogenetic and morphological evidence, six new species ( , , , , and ) are proposed and is recorded from China for the first time. The phylogenetic tree was constructed using ITS+LSU+TEF+ACT+RPB1 and the results were basically the same as ITS+LSU. All species of , except from fresh water, were isolated from soil. The genus is distributed worldwide, mainly in tropical and subtropical regions. A synoptic key is provided for a total of 24 species (18 species previously published and six species newly described herein), except for due to unavailable protologue, type and living culture. No morphologies were described when was proposed. Thanks to the strains isolated in this study, is included in the key and reported as a Chinese new record. This is the first comprehensive taxonomy and phylogeny of the genus .
半个多世纪以来，该属仅包含两个物种，而自2015年以来，该属已描述了多达17个新物种。然而，迄今为止尚未对该属进行系统研究。本文分析了该属所有已知物种的分布、基质和形态。同时，在系统发育和形态学证据的支持下，提出了六个新物种（ 、 、 、 、 和 ），并首次在中国记录到 。使用ITS+LSU+TEF+ACT+RPB1构建系统发育树，结果与ITS+LSU基本相同。该属的所有物种，除了来自淡水的 ，均从土壤中分离得到。该属分布于全球，主要在热带和亚热带地区。除了由于原始文献、模式标本和活培养物不可用而未纳入的 外，为总共24个物种（18个先前发表的物种和本文新描述的6个物种）提供了一个检索表。在提出 时未描述其形态。由于本研究中分离的菌株， 将被纳入检索表并作为中国新记录进行报道。这是该属的首次全面分类学和系统发育研究。
