Botryosphaeria 是一个物种丰富的属，具有世界性分布，通常与木本植物的顶枯病和溃疡病有关。多达 18 个无性型属与 Botryosphaeria 相关，其中大多数已被简化为 Diplodia（分生孢子大多为卵圆形、有色素、厚壁）或 Fusicaccum（分生孢子大多为梭形、透明、薄壁）的同义词。然而，有许多分生孢子无性型具有介于二倍体和梭菌属之间的形态特征，并且有一些关于葡萄球菌科之外的物种的记录，其具有明显典型的葡萄球菌属s.str的无性型。最近的研究还将 Botryosphaeria 与有色素、有隔膜的子囊孢子和 Dothiorella anamorphs 或 Fusicaccum anamorphs 与 Dichomera synanamorphs 的物种联系起来。本研究的目的是利用 28S rDNA 的 DNA 序列数据来解析葡萄球菌科内的明显谱系。从这些数据中，识别出 12 个进化枝。其中两个谱系聚集在 Botryosphaeriaceae 之外，即玉米上出现的类似 Diplodia 的无性型，最适合在 Stenocarpella (Diaporthales) 中，以及一个未解决的分支，包括 Camarosporium/Microdiplodia 物种。我们在 Botryosphaeriaceae 中识别出 10 个谱系，包括一个未解决的分支（Diplodia/Lasiodiplodia/Tiarosporella），Botryosphaeria s.str。 （Fusicaccum anamorphs）、Macrophomina、Neoscytalidium gen。 nov.，Dothidotthia（Dothiorella anamorphs），Neofusicoccum gen。十一月（Botryosphaeria 样有性型，Dichomera 样 synanamorphs），假梭菌属。 11 月，Saccharata（Fusicoccum 和 Diplodia 类无性型）、“Botryosphaeria”quercuum（Diplodia 类无性型）和 Guignardia（Phyllosticta 无性型）。没有为新引入的属提供单独的有性型和无性型名称，即使两个变体都是已知的。 由于缺乏前型培养物，一些分支和分离株（例如 B. mamane）的分类仍未解决。
Botryosphaeria is a species-rich genus with a cosmopolitan distribution, commonly associated with dieback and cankers of woody plants. As many as 18 anamorph genera have been associated with Botryosphaeria, most of which have been reduced to synonymy under Diplodia (conidia mostly ovoid, pigmented, thick-walled), or Fusicoccum (conidia mostly fusoid, hyaline, thin-walled). However, there are numerous conidial anamorphs having morphological characteristics intermediate between Diplodia and Fusicoccum, and there are several records of species outside the Botryosphaeriaceae that have anamorphs apparently typical of Botryosphaeria s.str. Recent studies have also linked Botryosphaeria to species with pigmented, septate ascospores, and Dothiorella anamorphs, or Fusicoccum anamorphs with Dichomera synanamorphs. The aim of this study was to employ DNA sequence data of the 28S rDNA to resolve apparent lineages within the Botryosphaeriaceae. From these data, 12 clades are recognised. Two of these lineages clustered outside the Botryosphaeriaceae, namely Diplodia-like anamorphs occurring on maize, which are best accommodated in Stenocarpella (Diaporthales), as well as an unresolved clade including species of Camarosporium/Microdiplodia. We recognise 10 lineages within the Botryosphaeriaceae, including an unresolved clade (Diplodia/Lasiodiplodia/Tiarosporella), Botryosphaeria s.str. (Fusicoccum anamorphs), Macrophomina, Neoscytalidium gen. nov., Dothidotthia (Dothiorella anamorphs), Neofusicoccum gen. nov. (Botryosphaeria-like teleomorphs, Dichomera-like synanamorphs), Pseudofusicoccum gen. nov., Saccharata (Fusicoccum- and Diplodia-like synanamorphs), “Botryosphaeria” quercuum (Diplodia-like anamorph), and Guignardia (Phyllosticta anamorphs). Separate teleomorph and anamorph names are not provided for newly introduced genera, even where both morphs are known. The taxonomy of some clades and isolates (e.g. B. mamane) remains unresolved due to the absence of ex-type cultures.
