Pezizomycotina 是子囊菌门最大的亚门，包括绝大多数丝状、产生子囊菌的物种。在这里，我们报告了来自 191 个分类群的 5 个核基因座（SSU rDNA、LSU rDNA、RPB1、RPB2 和 EF-1α）的加权简约性、最大似然性和贝叶斯系统发育分析的结果。目前已识别的 10 个盘菌亚门类中有 9 个在抽样中得到了体现。这些数据有力地支持了Pezizomycotina、Arthoniomycetes、Eurotiomycetes、Orbiliomycetes 和Sordariomycetes 的单系性。 Pezizomycetes 和 Dothideomycetes 也被解析为单系，但没有得到数据的有力支持。 Lecanoromycetes 在简约分析中被解析为并系，但在最大似然和贝叶斯分析中被解析为单系。由于排除了地舌菌科，Leotiomycetes 是多系的。 Pezizomycetes 的两个最基本的类别是 Orbiliomycetes 和 Pezizomycetes，两者都包含产生子囊子囊的物种。其余七个纲形成一个单系群，对应于Leotiomyceta。在Leotiomyceta 中，Leotiomycetes s.s. 的超纲分支。加上Sordariomycetes和Arthoniomycetes加上Dothideomycetes在适度的支持下得到了解决。
Pezizomycotina is the largest subphylum of Ascomycota and includes the vast majority of filamentous, ascoma-producing species. Here we report the results from weighted parsimony, maximum likelihood and Bayesian phylogenetic analyses of five nuclear loci (SSU rDNA, LSU rDNA, RPB1, RPB2 and EF-1α) from 191 taxa. Nine of the 10 Pezizomycotina classes currently recognized were represented in the sampling. These data strongly supported the monophyly of Pezizomycotina, Arthoniomycetes, Eurotiomycetes, Orbiliomycetes and Sordariomycetes. Pezizomycetes and Dothideomycetes also were resolved as monophyletic but not strongly supported by the data. Lecanoromycetes was resolved as paraphyletic in parsimony analyses but monophyletic in maximum likelihood and Bayesian analyses. Leotiomycetes was polyphyletic due to exclusion of Geoglossaceae. The two most basal classes of Pezizomycotina were Orbiliomycetes and Pezizomycetes, both of which comprise species that produce apothecial ascomata. The seven remaining classes formed a monophyletic group that corresponds to Leotiomyceta. Within Leotiomyceta, the supraclass clades of Leotiomycetes s.s. plus Sordariomycetes and Arthoniomycetes plus Dothideomycetes were resolved with moderate support.
