Rhizopus stolonifer

A very rapid-growing fungus that produces a reddish gray-brown colony within four days, when incubated at 25oC (77oF). It has worldwide distribution but is found primarily in the tropical and subtropical areas. It has been isolated from soil, desert soil, children=s sandpits, sand dunes, salt marshes, mines, bat caves, fresh and salt water, plants, and foodstuffs. Its role as an opportunistic human pathogen causing zygomycosis is questioned because of its inability to grow at 37oC (98.6oF).
