Chrysosporium and Some Other Aleuriosporic Hyphomycetes

A revised classification and nomenclature is proposed for some molds which produce hyaline, single-celled aleuriospores. Chrysosporium Corda is revived as a suitable genus for fungi which have been referred to Aleurisma Auct. non Link. Blastomyces, Emmonsia, Geomyces, Gilchristia, Glenosporella, Myceliophthora, and Zymonema are placed in synonymy under Chrysosporium. The typification and status of the following genera is discussed: Acladium, Aleurisma, Allescheriella, Bactridiopsis, Balanium, Blastomycoides, Botryotrichum, Chlamydomyces, Coccospora, Glenospora, Glenosporopsis, Histoplasma, Humicola, Mammaria, Monosporium, Monotospora, Myceliophthora, Mycogone, Oidium, Paracoccidioides, Rhinocladium, Scedosporium, Sepedonium, Sporothrix, Sporotrichum, Stephanoma, and Trichophyton.Chrysosporium asperatum and C. tropicum are proposed as new species. Six new combinations and one new name are proposed in Chrysosporium. One new combination is proposed in Paecilomyces. A key to the species of Chrysosporium is included as well as descriptions and illustrations of the species.
