一个六基因系统发育的Inocybaceae的家庭内的主要分支的分类地址。七属的确认，建立一个全球性的概述系统发育关系的Inocybaceae。新记录有假伞属和假子伞属。Inocybe-subg. Inosperma和subg.马洛西贝-被提升到通用级别。这四个新属，连同先前描述的Auritella，Tubariomyces，现在Inocybe sensu stricto，构成Inocybaceae，伞菌目的外生菌根谱系，与全球至少23个植物科相关。Pseudosperma，Nothocybe和Inocybe恢复作为一个强有力的支持包容性的分支内的家庭。Nothocybe属是Inocybe属的姐妹谱系，它是一个包含数百种和全球分布的高度多样性属。另外两个包容性分支，包括Inosperma、Tubariomyces、Auritella和Mallocybe，以及Auritella、Mallocybe和Tubariomyces的嵌套群，已被回收，但统计支持率很低。总体而言，六个基因的数据集提供了一个更强大的系统发育的家庭内的关系比单基因和单基因区域的估计。此外，非洲、印度和澳大利亚是该科最多的属，南美洲的属数最少。在Inosperma、Mallocybe和Pseudosperma中重新组合或提出新名称的共有180个。提供了丝孢菌科属检索表。
A six-gene phylogeny of the Inocybaceae is presented to address classification of major clades within the family. Seven genera are recognized that establish a global overview of phylogenetic relationships in the Inocybaceae. Two genera-Nothocybe and Pseudosperma-are described as new. Two subgenera of Inocybe-subg. Inosperma and subg. Mallocybe-are elevated to generic rank. These four new genera, together with the previously described Auritella, Tubariomyces, and now Inocybe sensu stricto, constitute the Inocybaceae, an ectomycorrhizal lineage of Agaricales that associates with at least 23 plant families worldwide. Pseudosperma, Nothocybe, and Inocybe are recovered as a strongly supported inclusive clade within the family. The genus Nothocybe, represented by a single species from tropical India, is strongly supported as the sister lineage to Inocybe, a hyperdiverse genus containing hundreds of species and global distribution. Two additional inclusive clades, including Inosperma, Tubariomyces, Auritella, and Mallocybe, and a nested grouping of Auritella, Mallocybe, and Tubariomyces, are recovered but with marginal statistical support. Overall, the six-gene data set provides a more robust phylogenetic estimate of relationships within the family than do single-gene and single-gene-region estimates. In addition, Africa, India, and Australia are characterized by the most genera in the family, with South America containing the fewest number of genera. A total of 180 names are recombined or proposed as new in Inosperma, Mallocybe, and Pseudosperma. A key to genera of Inocybaceae is provided.
