Species of are known as diminutive lepiotaceous fungi with a worldwide distribution. Previous studies revealed that is not monophyletic and preliminary DNA sequence data from recent collections suggested that several new species exist. Based on multi-locus DNA sequence data (the nuc rDNA internal transcribed spacer region ITS1-5.8S-ITS2, ITS; the D1-D2 domains of nuc 28S rDNA, LSU; the most variable region of the second-largest subunit of RNA polymerase II, and a portion of the translation-elongation factor 1-α. ), sect. forms a distinct clade separating from . Therefore, the genus was resurrected and two combinations, and were proposed. With the integration of morphological characteristics, multi-locus phylogeny, and information on geography and habitat, two new species, viz. and , are described and was revealed to be a species complex containing at least three species, viz. , , and . In addition, was re-circumscribed and neo-typified based on recent collections.
[该属物种]被认为是分布于全球的小型鳞伞科真菌。先前的研究表明[该属]并非单系类群，近期采集样本的初步DNA序列数据表明存在几个新物种。基于多位点DNA序列数据（核糖体DNA内部转录间隔区ITS1 - 5.8S - ITS2，即ITS；核糖体28S rDNA的D1 - D2结构域，即LSU；RNA聚合酶II第二大亚基的最大可变区，以及翻译延伸因子1 - α的一部分），[该属的某组]形成了一个与[另一组]分离的独特分支。因此，[该属]被重新启用，并提出了两个新组合，即[组合一]和[组合二]。结合形态特征、多位点系统发育以及地理和栖息地信息，描述了两个新物种，即[新物种一]和[新物种二]，并且揭示[某物种]是一个包含至少三个物种的复合物种，即[物种一]、[物种二]和[物种三]。此外，基于近期采集的样本对[另一物种]进行了重新界定和新指定模式。
