我们研究了两个物种的系统发育关系，模仿球毛壳菌的有性型和无性型形态，球毛壳菌tulasneorum与一个dendrotrichum无性型和澳大利亚昆士兰与Dischloridium无性型。分析了四个数据集：a）包括ITS 1、5.8S rDNA和ITS 2（ITS）的内转录间隔区，B）nc 28 S（ncLSU）rDNA，c）nc 18 S（ncSSU）rDNA，和d）ncLSU-ncSSU-RPB 2（核糖体聚合酶B2）的组合数据集。传统的基于ncLSU序列的Ch. tulasneorum在Microascales中的位置是不支持的，并且Australiasca不属于Chaetosphaeriaceae。这两种全型物种都嵌套在Glomerellales中。本文介绍了一个新属-阐明了球囊霉目的分类结构，并有效地公布了该名称。如这里所界定的，它包括三个科，球囊菌科和新描述的澳大利亚和网状菌科。基于ITS和ncLSU rDNA序列分析，我们确认了无性型属Dischloridium与Monilochaelum的同义关系。因此，该属的模式种Dischloridium laeënse和三个相关物种被转移到更古老的Monilochaelae属。D.在澳大利亚，laeënse被描述为一个新种。在三基因系统发育中，垂球壳科是球壳目的基础，其上又增加了无性型属--水囊藻属。环纹散藻（Stilbella annulata）也属于该科，是一个新组合.基于ncLSU、ncSSU和组合ncLSU-ncSSU-RPB 2序列的系统发育分析阐明了微囊藻内的家族关系。Ceratocystidaceae被确认为一个强有力的单系群，包括Ceratocystis，Cornuvesica，Thielaviopsis和Ambrosiella的模式种。新的科Gondwanamycetaceae，一个强烈支持的姐妹分支的Ceratocystidaceae，介绍了有性型属Gondwanamyces和它的Cutingophora anamorphs。微囊藻目有四个科，即Ceratocystidaceae、Gondwanamycetaceae、Halosphaeriaceae和Microascaceae。由于一个建议的亲和力Faurelina indica分离的Microascales，Chadefaudiellaceae的系统发育位置重新评估。 基于来自对Dothideomycetes的单独ncLSU分析的结果，将Faurelina从微囊藻目中排除，并将其置于Pleosporales中。
We examined the phylogenetic relationships of two species that mimic Chaetosphaeria in teleomorph and anamorph morphologies, Chaetosphaeria tulasneorum with a Cylindrotrichum anamorph and Australiasca queenslandica with a Dischloridium anamorph. Four data sets were analysed: a) the internal transcribed spacer region including ITS1, 5.8S rDNA and ITS2 (ITS), b) nc28S (ncLSU) rDNA, c) nc18S (ncSSU) rDNA, and d) a combined data set of ncLSU-ncSSU-RPB2 (ribosomal polymerase B2). The traditional placement of Ch. tulasneorum in the Microascales based on ncLSU sequences is unsupported and Australiasca does not belong to the Chaetosphaeriaceae. Both holomorph species are nested within the Glomerellales. A new genus, Reticulascus, is introduced for Ch. tulasneorum with associated Cylindrotrichum anamorph; another species of Reticulascus and its anamorph in Cylindrotrichum are described as new. The taxonomic structure of the Glomerellales is clarified and the name is validly published. As delimited here, it includes three families, the Glomerellaceae and the newly described Australiascaceae and Reticulascaceae. Based on ITS and ncLSU rDNA sequence analyses, we confirm the synonymy of the anamorph genera Dischloridium with Monilochaetes. Consequently Dischloridium laeënse, type species of the genus, and three related species are transferred to the older genus Monilochaetes. The teleomorph of D. laeënse is described in Australiasca as a new species. The Plectosphaerellaceae, to which the anamorph genus Stachylidium is added, is basal to the Glomerellales in the three-gene phylogeny. Stilbella annulata also belongs to this family and is newly combined in Acrostalagmus. Phylogenetic analyses based on ncLSU, ncSSU, and combined ncLSU-ncSSU-RPB2 sequences clarify family relationships within the Microascales. The family Ceratocystidaceae is validated as a strongly supported monophyletic group consisting of Ceratocystis, Cornuvesica, Thielaviopsis, and the type species of Ambrosiella. The new family Gondwanamycetaceae, a strongly supported sister clade to the Ceratocystidaceae, is introduced for the teleomorph genus Gondwanamyces and its Custingophora anamorphs. Four families are accepted in the Microascales, namely the Ceratocystidaceae, Gondwanamycetaceae, Halosphaeriaceae, and Microascaceae. Because of a suggested affinity of a Faurelina indica isolate to the Microascales, the phylogenetic position of the Chadefaudiellaceae is reevaluated. Based on the results from a separate ncLSU analysis of the Dothideomycetes, Faurelina is excluded from the Microascales and placed in the Pleosporales.
