Fresh collections, type studies and molecular phylogenetic analyses of a multigene matrix of partial nuSSU-ITS-LSU rDNA, , and sequences were used to evaluate the boundaries of in a strict sense and of several related genera of the . Two species are recognised in and 19 in . The monotypic genera , , , , and are described as new. is here included as its generic type (= ), which is lecto- and epitypified. and are combined in . Asexual morphs of , where known, are all pyrenochaeta- or phoma-like. Comparison of the phylogenetic analyses of the ITS-LSU and combined matrices demonstrate that at least sequences should be added whenever possible to improve phylogenetic resolution of the tree backbone; in addition, the introns should be added as well to improve delimitation of closely related species.
利用新鲜采集样本、模式研究以及对部分核小亚基核糖体DNA（nuSSU）-内转录间隔区（ITS）-大亚基核糖体DNA（LSU）、、和序列的多基因矩阵进行分子系统发育分析，以严格评估狭义的边界以及几个相关属的边界。在中识别出两个物种，在中识别出19个物种。单型属、、、、和被描述为新属。在此被归入其模式种（=），并进行了选模式和后选模式的指定。和被合并到中。已知的无性型形态均类似壳囊孢属或茎点霉属。对ITS-LSU和联合矩阵的系统发育分析比较表明，只要有可能，应至少添加序列以提高系统发育树主干的分辨率；此外，还应添加内含子以改善近缘物种的界定。
