Phoma组分离物的18S nrDNA(SSU)和28S nrDNA(LSU)区序列数据。将副瘤菌与形态相似的侧耳藻属和核毛虫属的代表性菌株以及模式种Phonza、Pilosa和Plenodomus进行了比较。福玛区。副孢子瘤在Pleosporales中是高度多系的，仅与Phoma组Phoma有较远的亲缘关系。Paraphonza属(Paraphonza)是以根副瘤为基础的，在棕榈科中重新引入，并增加了两个分类单元。新属和新变种，模式种Setopoma terrestris comb.11月和新油菜Neosetopoma samarorum comb.Nov.，它们代表了与副瘤关系密切但在形态特征和分子系统发育上存在差异的种。Coonsii被转移到同属棕榈科的毛壳藻属。核毛壳菌属11月为适应模式种细小孢霉Prenochaetopsis Leptospora comb.Nov.，以及以前在Phoma和Prenochaeta栖息的其他几个种。核毛委陵菜属于葫芦科，与核壳菌有密切的亲缘关系。Pleurophoma CAVA被转移到Prenochaeta属。新属阐明了属内种的混乱的分类。Pomoma、Prenochaeta和Pleurophoma，并识别单系属，具有明显的染色体亲缘关系。
Sequence data from the 18S nrDNA (SSU) and 28S nrDNA (LSU) regions of isolates of Phoma section. Paraphoma were compared with those of representative isolates of the morphologically similar an am orph genera Pleurophoma and Pyrenochaeta and of the type species of Phoma sections Phonza, Pilosa and Plenodomus. Phoma section. Paraphoma was found to be highly polyphyletic within the Pleosporales and only distantly related to Phoma section Phoma. The genus Paraphonza, which is based on Paraphoma radicina, is reintroduced in the Phaeosphaeriaceae with two additional taxa. The new genera Setophoma and Neosetophoma, type species Setophoma terrestris comb. nov. and Neosetophoma samarorum comb. nov., are introduced and represent species that are closely related to Paraphoma but differ based on morphological characters and molecular phylogeny. Phoma coonsii is transferred to genus Chaetosphaeronema that also belongs to the Phaeosphaeriaceae. Pyrenochaetopsis gen. nov. is introduced to accommodate the type species Pyrenochaetopsis leptospora comb. nov., as well as several other species formerly accommodated in Phoma and Pyrenochaeta. Pyrenochaetopsis is closely related to Pyrenochaela and classified in the Cucurbitariaceae. Pleurophoma cava is transferred to genus Pyrenochaeta. The new genera elucidate the confusing taxonomy of species in genera. Phoma, Pyrenochaeta and Pleurophoma and recognize monophyletic genera with distinct teleomorph affinities.
