Zygomycetes Sporobolomyces spp. 1924 Description Colonies are rapid growing, smooth, often wrinkled, glistening to dull, bright red to orange in color. Pseudohyphae and hyphae often, are abundant and well developed. Ballistoconidia are 1-celled, usually reniform, forcibly discharged from denticles on ovoid to elongate vegetative cells. Blastoconidia are the most common type of conidia.
Fermentation is absent.
Salient characteristics Sporobolomyces is recognized by its development of red to orange colonies and by its typically reniform ballistoconidia, which may be abundant enough to form a mirror image of the colony on nutrient agar on the lid of an inverted Petri plate. Teleomorph Sporidiobolus Sporobolomyces salmonicolor, members of this genus produce ballistoconidia upon denticles.
