Chrysosporium is a genus of hyaline hyphomycetes Fungus in the family Onygenaceae.
Chrysosporium colonies are moderately fast-growing, flat, white to tan to beige in color; they often have a powdery or granular surface texture. Hyaline, one-celled (ameroconidia) are produced directly on vegetative hyphae by non-specialized conidiogenous cells. Conidia are typically to clavate with truncate bases (6 to 7 by 3.5 to 4 um) and are formed either (arthroconidia), laterally (often on pedicels), or terminally.
Clinical significance
Species of
Chrysosporium are occasionally isolated from skin and nail scrapings, especially from feet, but, because they are common soil
saprotrophs, they are usually considered as contaminants. There are about 22 species of Chrysosporium, several are
keratinophilic with some also being
thermotolerant, and cultures may closely resemble some
dermatophytes, especially
Trichophyton mentagrophytes, and some strains may also resemble cultures of
Histoplasma and
Blastomyces
Chrysosporium has been identified as an emerging infectious disease, first in Canada affecting at around 1995.[
