球壳菌纲是子囊菌门中最大的纲之一，其大多数种的特征是具囊壳的子囊和无盖的单囊。它包括600多个属，3000多个种，代表了广泛的生态学，包括植物病原体和内生菌，动物病原体和真菌寄生虫。为了测试和改进Sordariomycetes sensu Eriksson（2006）的分类，基于四个核基因座（nSSU和nLSU rDNA，TEF和RPB 2），使用三种Leotiomycetes作为外群，研究了来自16种Sordariomycetes中的12个目的106个分类群之间的系统发育关系。Lulworthiales在Sordariomycetes的基群或Hypocreomycetidae的姐妹群中的位置很好地支持了目前在分类中公认的三个子类（即Hypocreomycetidae，Sordariomycetidae和Xylariomycetidae）。除了微囊藻目，我们的结果承认大部分的订单作为单系群。黑孢菌属（Melanospora）是肉座菌目（Hypocreales）之外的一个分支，被认为是肉座菌科（Hypocreomycetidae）中的一个独立目。球囊霉科被排除在叶藓目之外，并被置于Hypocreomycetidae incertae sedis中。在索氏菌科中，索氏菌目是一个强有力的支持分支，并出现在包含Boliniales和Chaetosphaeriales的一个支持良好的分支中。形态学，生态学和进化方面进行了讨论。
The Sordariomycetes is one of the largest classes in the Ascomycota, and the majority of its species are characterized by perithecial ascomata and inoperculate unitunicate asci. It includes more than 600 genera with over 3000 species and represents a wide range of ecologies including pathogens and endophytes of plants, animal pathogens and mycoparasites. To test and refine the classification of the Sordariomycetes sensu Eriksson (2006), the phylogenetic relationship among 106 taxa from 12 orders out of 16 in the Sordariomycetes was investigated based on four nuclear loci (nSSU and nLSU rDNA, TEF and RPB2), using three species of the Leotiomycetes as outgroups. Three subclasses (i.e. Hypocreomycetidae, Sordariomycetidae and Xylariomycetidae) currently recognized in the classification are well supported with the placement of the Lulworthiales in either a basal group of the Sordariomycetes or a sister group of the Hypocreomycetidae. Except for the Microascales, our results recognize most of the orders as monophyletic groups. Melanospora species form a clade outside of the Hypocreales and are recognized as a distinct order in the Hypocreomycetidae. Glomerellaceae is excluded from the Phyllachorales and placed in Hypocreomycetidae incertae sedis. In the Sordariomycetidae, the Sordariales is a strongly supported clade and occurs within a well supported clade containing the Boliniales and Chaetosphaeriales. Aspects of morphology, ecology and evolution are discussed.
