Reclassification of Cladosporium bantianum in the genus Xylohypha

It is proposed that the dematiaceous hyphomycete Cladosporium bantianum (Saccardo) Borelli be transferred to the genus Xylohypha (Fries) Mason as Xylohypha bantiana (Saccardo) McGinnis, Padhye, Borelli, et Ajello. This new combination is necessary because X. bantiana produces conidiophores that are indistinguishable from its vegetative hyphae and one-celled, smooth-walled conidia that are borne in long, infrequently branched chains. The blastoconidia do not possess darkly pigmented hila. In contrast, members of the genus Cladosporium Link produce erect, distinct conidiophores and one- to four-celled smooth-to-rough-walled conidia that occur in short, frequently branched, fragile chains. The blastoconidia have darkly pigmented hila. Cladosporium trichoides Emmons is a later synonym of X. bantiana.
