我们从物种中扩增了RPB1、RPB2以及ITS和LSU核糖体基因，主要集中在裸角类分类群中。我们对不同的数据集组合进行了最大似然和贝叶斯分析。我们的结果提供了一个强有力的支持的系统发育图，代表了四个基因分析中的89个种，其中49个代表裸角类分类群。隐毛裸毛虫是一个多系种，分布于根茎纲的9个谱系中。这些谱系中有六个与已描述的属相关联，而我们描述的新属Phaephlebisis是为了适应其中一个剩余的谱系中类似Phlebisis的物种。我们还提出了三个分类转移，并描述了九个新种，其中四个种目前被归入血色原毛平革菌或绒毛原毛平革菌。最后，毛细管菌和其他潜在的褐腐菌物种在根茎类分支中的位置表明，除了Antrodia分支外，褐腐菌可能在多孔菌目中进化了不止一次。(C)2015年英国真菌学会。爱思唯尔有限公司出版。保留所有权利。
We amplified RPB1, RPB2, and the ITS and LSU ribosomal genes from species mostly in the phlebioid clade, focusing heavily in phanerochaetoid taxa. We performed Maximum Likelihood and Bayesian analyses for different combinations of datasets. Our results provide a strongly supported phylogenetic picture of the phlebioid clade, representing 89 species in the four genes analyses, of which 49 represent phanerochaetoid taxa. Phanerochaete sensu lato is polyphyletic and distributed across nine lineages in the phlebioid clade. Six of these lineages are associated to already described genera, while we describe the new genus Phaeophlebiopsis to accommodate Phlebiopsis-like species in one of the remaining lineages. We also propose three taxonomic transfers and describe nine new species, with four of those species currently placed in Phanerochaete sanguinea or Phanerochaete velutina. Finally, the placement of Leptoporus mauls along with other potential brown-rot species in the phlebioid clade suggests that, in addition to the Antrodia clade, brown-rot fungi may have evolved more than once in Polyporales.
