Five loci, nucSSU, nucLSU rDNA, TEF1, RPB1 and RPB2, are used for analysing 129 pleosporalean taxa representing 59 genera and 15 families in the current classification of Pleosporales. The suborder Pleosporineae is emended to include four families, viz.Didymellaceae, Leptosphaeriaceae, Phaeosphaeriaceae and Pleosporaceae. In addition, two new families are introduced, i.e. Amniculicolaceae and Lentitheciaceae. Pleomassariaceae is treated as a synonym of Melanommataceae, and new circumscriptions of Lophiostomataceaes. str., Massarinaceae and Lophiotrema are proposed. Familial positions of Entodesmium and Setomelanomma in Phaeosphaeriaceae, Neophaeosphaeria in Leptosphaeriaceae, Leptosphaerulina, Macroventuria and Platychora in Didymellaceae, Pleomassaria in Melanommataceae and Bimuria, Didymocrea, Karstenula and Paraphaeosphaeria in Montagnulaceae are clarified. Both ecological and morphological characters show varying degrees of phylogenetic significance. Pleosporales is most likely derived from a saprobic ancestor with fissitunicate asci containing conspicuous ocular chambers and apical rings. Nutritional shifts in Pleosporales likely occured from saprotrophic to hemibiotrophic or biotrophic.
五个基因座，核 SSU、核 LSU rDNA、TEF1、RPB1 和 RPB2，用于分析 Pleosporales 目目前分类中代表 59 属和 15 科的 129 个 Pleosporalean 分类单元。拟盘多毛孢亚目被修订为包括四个科，即拟盘多毛孢科、长喙壳科、腔孢壳科和拟盘多毛孢科。此外，还引入了两个新科，即枝孢腔菌科和 Lentitheciaceae。拟盘多毛孢科被视为 Melanommataceae 的同义词，Lophiostomataceae.str.、Massarinaceae 和 Lophiotrema 的定义也得到了修改。拟盘多毛孢科中 Entodesmium 和 Setomelanomma、长喙壳科中的 Neophaeosphaeria、拟盘多毛孢科中的 Leptosphaerulina、Macroventuria 和 Platychora、Melanommataceae 中的 Pleomassaria 以及 Montagnulaceae 中的 Bimuria、Didymocrea、Karstenula 和 Paraphaeosphaeria 的科地位得到了澄清。生态和形态特征都显示出不同程度的系统发育意义。盘菌目可能起源于一种腐生祖先，其具有裂生厚壁的子囊，含有明显的眼室和顶环。盘菌目的营养方式可能从腐生转变为半活体营养或活体营养。
