Cladosporium musae, a widespread leaf-spotting hyphomycete on Musa spp., is genetically and morphologically distinct from Cladosporium s. str. (Davidiella anamorphs, Mycosphaerellaceae, Dothideales). DNA sequence data derived from the ITS and LSU gene regions of C. musae isolates show that this species is part of a large group of hyphomycetes in the Chaetothyriales with dematiaceous blastoconidia in acropetal chains. Cladosporium adianticola, a foliicolous hyphomycete known from leaf litter in Cuba is also a member of this clade and is closely related to C. musae. A comparison with other genera in the Cladosporium complex revealed that C. musae belongs to a lineage for which no generic name is currently available, and for which the genus Metulocladosporiella gen. nov. is proposed. Two species of Metulocladosporiella are currently known, namely M. musae, which is widely distributed, and M. musicola sp. nov., which is currently known from Africa.
香蕉枝孢菌是香蕉属植物上广泛存在的一种叶斑丝孢菌，在遗传和形态上与狭义枝孢菌（大卫氏菌无性型，球腔菌科，座囊菌目）不同。从香蕉枝孢菌分离株的ITS和LSU基因区域获得的DNA序列数据表明，该物种是座囊菌目中一大群丝孢菌的一部分，其深色芽生孢子呈向顶链状排列。古巴叶凋落物中发现的叶生丝孢菌——铁线莲枝孢菌也是该分支的成员，且与香蕉枝孢菌密切相关。与枝孢菌复合体中的其他属进行比较后发现，香蕉枝孢菌属于一个目前尚无通用名称的谱系，为此提出了新属——拟枝顶孢属。目前已知拟枝顶孢属有两个物种，即广泛分布的香蕉拟枝顶孢和目前仅在非洲发现的新物种——嗜蕉拟枝顶孢。
