Mucor hiemalis form hiemalis
A rapidly-growing fungus that produces a white to yellow colony, later becoming dark gray within four days, when incubated at 25oC (77oF). It is found worldwide and is one of the most common fungi found in the environment. It can be isolated from air, soil, salt marshes, children’s sandpits, dunes, sandy soil, desert soil, river water, sewage sludge, animal dung, bird feathers, garden compost, and decaying plant materials. Rarely, it can be an opportunistic human pathogen.
