枝孢属是暗色丝孢纲中最大的属之一，其特征是冠状疤痕结构，顶生链中的分生孢子和Davidiella teleomorphs。根据形态学和DNA序列分析，确定了C.草类和C. sphaerospermum已经解决，在许多新的分类群的澄清。在本研究中，200多个菌株属于C。根据核核糖体RNA基因操纵子的DNA序列，包括内转录间隔区ITS 1和ITS 2，5.8S nrDNA，以及部分肌动蛋白和翻译延伸因子1-α基因序列，对枝孢复合体进行了检测和遗传学分析。对于腐，广泛分布的种枝孢Cladosporium cladosporioides，新模式和表型都指定，以指定一个良好建立的界限和本种的概念。Cladosporium tenuissimum和C. oxysporum是两种在热带地区大量存在的腐殖菌，它们与C.枝孢类 根据系统发育特征和隐蔽的形态学差异，新描述了22个种。对不同种间的主要表型性状进行了分析。cladosporioides复合体代表了该属内的一个单系亚支，其特征是分生孢子和分生孢子梗的形状、宽度、长度、分隔和表面排列，分生孢子链的长度和分枝方式以及菌丝的形状、宽度和排列。许多被处理的物种，例如， C. acadhae、刺萼C.狭孢C. australiense，C. basiinflatum，C. chalastosporoides，C. colocasiae、芋头C. cucumerinum、黄瓜C. acetuatum、C. exile，C. flabelliforme、扇叶拟步行虫C. gamsianum和C. globisporum目前仅知道来自特定的宿主，或者具有有限的地理分布。一个能识别所有在C. 提供了枝孢复合体。
The genus Cladosporium is one of the largest genera of dematiaceous hyphomycetes, and is characterised by a coronate scar structure, conidia in acropetal chains and Davidiella teleomorphs. Based on morphology and DNA phylogeny, the species complexes of C. herbarum and C. sphaerospermum have been resolved, resulting in the elucidation of numerous new taxa. In the present study, more than 200 isolates belonging to the C. cladosporioides complex were examined and phylogenetically analysed on the basis of DNA sequences of the nuclear ribosomal RNA gene operon, including the internal transcribed spacer regions ITS1 and ITS2, the 5.8S nrDNA, as well as partial actin and translation elongation factor 1-α gene sequences. For the saprobic, widely distributed species Cladosporium cladosporioides, both a neotype and epitype are designated in order to specify a well established circumscription and concept of this species. Cladosporium tenuissimum and C. oxysporum, two saprobes abundant in the tropics, are epitypified and shown to be allied to, but distinct from C. cladosporioides. Twenty-two species are newly described on the basis of phylogenetic characters and cryptic morphological differences. The most important phenotypic characters for distinguishing species within the C. cladosporioides complex, which represents a monophyletic subclade within the genus, are shape, width, length, septation and surface ornamentation of conidia and conidiophores; length and branching patterns of conidial chains and hyphal shape, width and arrangement. Many of the treated species, e.g., C. acalyphae, C. angustisporum, C. australiense, C. basiinflatum, C. chalastosporoides, C. colocasiae, C. cucumerinum, C. exasperatum, C. exile, C. flabelliforme, C. gamsianum, and C. globisporum are currently known only from specific hosts, or have a restricted geographical distribution. A key to all species recognised within the C. cladosporioides complex is provided.
