胶孢炭疽菌物种复合体的限制是基于炭疽菌 ITS 基因树内强有力支持的进化枝而从遗传学上定义的。该分支中接受的所有类群在形态上或多或少都具有广义定义的 C. gloeosporioides 的典型特征，因为它已在过去 50 年的文献中得到应用。我们接受 C. gloeosporioides 复合体中的 22 个物种和一个亚种。这些包括 C. asianum、C. cordylinicola、C. fructicola、C. gloeosporioides、C. horii、C. kahawae subsp.。 kahawae、C. musae、C. nupharicola、C. psidii、C. siamense、C. theobromicola、C.tropice 和 C. xanthorrhoeae，以及此处描述为新的分类群、C. aenigma、C. aeschynomenes、C. alatae、C. Alinum、C. aotearoa、C. clidemiae、C. kahawae subsp。 ciggaro、C. salsolae 和 C. ti，加上化名。十一月C. Queenslandicum（C. gloeosporioides var. minus）。所有分类单元都是基于多基因系统发育的遗传定义。对于没有现代描述的物种，提供了简短的形态描述。许多物种无法使用真菌的官方条形码基因 ITS 进行可靠区分。特别有问题的是一组在遗传上与 C. musae 接近的物种和另一组在遗传上与 C. kahawae 接近的物种，这里分别称为 Musae 分支和 Kahawae 分支。每个分支包含几个在多基因分析中得到系统发育良好支持的物种，但由于系统发育信息特征数量较少，分支内部的分支长度很短，并且在少数情况下单个基因树不一致。一些单基因或基因组合，例如3-磷酸甘油醛脱氢酶和谷氨酰胺合成酶，可用于可靠地区分大多数分类单元，并且需要开发为用于物种水平鉴定的二级条形码，这很重要，因为许多这些真菌具有生物安全意义。除了公认的物种之外，还提供了一些名称的注释，这些名称可能与最近的文献中提出的 C. gloeosporioides sensu lato 存在密切关系，以及 C. gloeosporioides 及其推定的有性型 Glomerella cingulata 内的所有亚种分类群和特殊形式。名称替换 - C. queenslandicum B.

The limit of the Colletotrichum gloeosporioides species complex is defined genetically, based on a strongly supported clade within the Colletotrichum ITS gene tree. All taxa accepted within this clade are morphologically more or less typical of the broadly defined C. gloeosporioides, as it has been applied in the literature for the past 50 years. We accept 22 species plus one subspecies within the C. gloeosporioides complex. These include C. asianum, C. cordylinicola, C. fructicola, C. gloeosporioides, C. horii, C. kahawae subsp. kahawae, C. musae, C. nupharicola, C. psidii, C. siamense, C. theobromicola, C. tropicale, and C. xanthorrhoeae, along with the taxa described here as new, C. aenigma, C. aeschynomenes, C. alatae, C. alienum, C. aotearoa, C. clidemiae, C. kahawae subsp. ciggaro, C. salsolae, and C. ti, plus the nom. nov. C. queenslandicum (for C. gloeosporioides var. minus). All of the taxa are defined genetically on the basis of multi-gene phylogenies. Brief morphological descriptions are provided for species where no modern description is available. Many of the species are unable to be reliably distinguished using ITS, the official barcoding gene for fungi. Particularly problematic are a set of species genetically close to C. musae and another set of species genetically close to C. kahawae, referred to here as the Musae clade and the Kahawae clade, respectively. Each clade contains several species that are phylogenetically well supported in multi-gene analyses, but within the clades branch lengths are short because of the small number of phylogenetically informative characters, and in a few cases individual gene trees are incongruent. Some single genes or combinations of genes, such as glyceraldehyde-3-phosphate dehydrogenase and glutamine synthetase, can be used to reliably distinguish most taxa and will need to be developed as secondary barcodes for species level identification, which is important because many of these fungi are of biosecurity significance. In addition to the accepted species, notes are provided for names where a possible close relationship with C. gloeosporioides sensu lato has been suggested in the recent literature, along with all subspecific taxa and formae speciales within C. gloeosporioides and its putative teleomorph Glomerella cingulata.
