Sepedonium species

A moderately rapidly-growing fungus that produces a white, later yellow colony with a white reverse, within seven days, when incubated at 25oC (77oF). It has worldwide distribution and can be isolated from soil. It can be confused with the fungal pathogen Histoplasma capsulatum because it produces large, round, thick walled, rough or knobby macroconidia. However, it can be differentiated from H. capsulatum by not forming microconidia, by not converting to a yeast when grown at 35oC, and by its rapid growth rate. It is not pathogenic for humans.
