The genus Scedosporium and its relatives comprising microascalean anamorphs with slimy conidia were studied. Graphium and Parascedosporium also belong to this complex, while teleomorphs are found in Pseudallescheria, Petriella, Petriellopsis, and Lophotrichus. Species complexes were clearly resolved by rDNA ITS sequencing. Significantly different ecological trends were observed between resolved species aggregates. The Pseudallescheria and Scedosporium prolificans clades were the only lineages with a marked opportunistic potential to mammals, while Petriella species were associated primarily with soil enriched by, e.g. dung. A consistent association with bark beetles was observed in the Graphium clade. The ex-type strain of Rhinocladium lesnei, CBS 108.10 was incorrectly implicated by Vuillemin (1910) in a case of human mycetoma; its sequence was identical to that of the ex-type strain of Parascedosporium tectonae, CBS 127.84.
对包括粘性分生孢子的微尺度无性型在内的帚梗霉属及其近缘种进行了研究。Graphium 和 Parascedosporium 也属于这个复合体，而其有性型则存在于拟青霉属、皮壳属、皮壳孢属和丝孢腔菌属中。rDNA ITS 测序清楚地区分了种复合体。已解决的物种聚集体之间观察到明显不同的生态趋势。假丝酵母属和 Scedosporium prolificans 枝系是唯一具有明显机会主义倾向的哺乳动物的谱系，而皮壳属物种主要与富含例如粪便的土壤有关。Graphium 枝系与树皮甲虫有一致的关联。假丝酵母属 Rhinocladium lesnei，CBS 108.10 的模式菌株被 Vuillemin（1910）错误地牵涉到一例人类真菌性足菌肿中；其序列与 Parascedosporium tectonae，CBS 127.84 的模式菌株完全相同。
