利用内转录间隔区（ITS 1、ITS 2）和5.8S基因以及18 S rRNA基因的序列数据对不同类枝孢丝孢菌进行系统发育研究，结果表明，类枝孢丝孢属（Cladosporium）的5.8S基因和18 S rRNA基因是一个完整的系统发育基因。lat. to be heterogeneous异构.枝孢属Cladosporium s. str.是Mycosphaerella s的姐妹分支。字符串，因此提出将其命名为真形类Davidiella属。在此基础上，讨论了枝孢类真菌的形态学、系统发育和分类学问题。枝孢属局限于Davidiella（球腔菌科）无性型，具有冠状分生孢子位点和分生孢子脐。假枝孢属（Pseudocladosporium）仅限于卡普罗文氏菌属（Venturiaceae）的无性型。黑星菌属的枝孢状无性型（链状分生孢子）被称为Fusicladium。人类致病性的枝孢属物种属于Cladophialophora（Capronia，Herpotrichiellaceae），而黄枝孢属是球腔菌属/钉孢属分支（Mycosphaerellaceae）的代表。Cladosporium malorum被证明为Pseudocladosporium kellermanianum（syn. Phaeoramularia kellermaniana，Cladophialophora kellermaniana）以及Cladosporium porophorum。基于分生孢子发生和分生孢子发生位点结构的差异，并进一步得到分子生物学数据的支持，C。malorum属于链格孢属（Alternaria）。
A phylogenetic study employing sequence data from the internal transcribed spacers (ITS1, ITS2) and 5.8S gene, as well as the 18S rRNA gene of various Cladosporium-like hyphomycetes revealed Cladosporium s. lat. to be heterogeneous. The genus Cladosporium s. str. was shown to represent a sister clade to Mycosphaerella s. str., for which the teleomorph genus Davidiella is proposed. The morphology, phylogeny and taxonomy of the cladosporioid fungi are discussed on the basis of this phylogeny, which consists of several clades representing Cladosporium-like genera. Cladosporium is confined to Davidiella (Mycosphaerellaceae) anamorphs with coronate conidiogenous loci and conidial hila. Pseudocladosporium is confined to anamorphs of Caproventuria (Venturiaceae). Cladosporium-like anamorphs of the Venturia (conidia catenate) are referred to Fusicladium. Human-pathogenic Cladosporium species belong in Cladophialophora (Capronia, Herpotrichiellaceae) and Cladosporium fulvum is representative of the Mycosphaerella/Passalora clade (Mycosphaerellaceae). Cladosporium malorum proved to provide the correct epithet for Pseudocladosporium kellermanianum (syn. Phaeoramularia kellermaniana, Cladophialophora kellermaniana) as well as Cladosporium porophorum. Based on differences in conidiogenesis and the structure of the conidiogenous loci, further supported by molecular data, C. malorum is allocated to Alternaria.
