We present an expanded multigene phylogeny of the Dothideomycetes. The final data matrix consisted of four loci (nuc SSU rDNA, nuc LSU rDNA, TEF1, RPB2) for 96 taxa, representing five of the seven orders in the current classification of Dothideomycetes and several outgroup taxa representative of the major clades in the Pezizomycotina. The resulting phylogeny differentiated two main dothideomycete lineages comprising the pseudoparaphysate Pleosporales and aparaphysate Dothideales. We propose the subclasses Pleosporomycetidae (order Pleosporales) and Dothideomycetidae (orders Dothideales, Capnodiales and Myriangiales). Furthermore we provide strong molecular support for the placement of Mycosphaerellaceae and Piedraiaceae within the Capnodiales and introduce Davidiellaceae as a new family to accommodate species of Davidiella with Cladosporium anamorphs. Some taxa could not be placed with certainty (e.g. Hysteriales), but there was strong support for new groupings. The clade containing members of the genera Botryosphaeria and Guignardia resolved well but without support for any relationship to any other described orders and we hereby propose the new order Botryosphaeriales. These data also are consistent with the removal of Chaetothyriales and Coryneliales from the Dothideomycetes and strongly support their placement in the Eurotiomycetes.
我们展示了座囊菌纲扩展的多基因系统发育树。最终的数据矩阵由96个分类单元的四个基因座（核糖体小亚基核糖核酸、核糖体大亚基核糖核酸、延伸因子1、RNA聚合酶II第二大亚基）组成，代表了座囊菌纲当前分类中七个目里的五个目以及几个外类群分类单元，这些外类群代表了粪壳菌亚纲中的主要进化枝。由此产生的系统发育树区分出两个主要的座囊菌谱系，包括具假侧丝的格孢腔菌目和无侧丝的座囊菌目。我们提出了格孢腔菌亚纲（格孢腔菌目）和座囊菌亚纲（座囊菌目、煤炱目和多腔菌目）。此外，我们为球腔菌科和 piedraiaceae 在煤炱目内的位置提供了有力的分子支持，并引入了小穴壳菌科作为一个新科，以容纳具有枝孢菌无性型态的小穴壳菌属物种。一些分类单元无法确定其位置（例如肉座菌目），但对新的分类群有很强的支持。包含葡萄座腔菌属和球座菌属成员的进化枝解析良好，但不支持与任何其他已描述目的任何关系，我们在此提出新目葡萄座腔菌目。这些数据也与将散囊菌目和棒囊菌目从座囊菌纲中移除一致，并有力支持它们在散囊菌纲中的位置。
