Rhizopus rhizopodiformis (Rhizopus microsporus variety rhizopodiformis): A very rapidly growing fungus that produces a gray to dark brownish-gray colony within four days, when incubated at 25C (77F).  It has worldwide distribution but is found primarily in the tropical and subtropical areas.  It has been isolated from soil, salt marshes, mines, caves, bat guano, bird feathers, fresh and salt water, plants, and foodstuffs. 
 
Clinical Relevance:
 
R. rhizopodiformis is an opportunistic human pathogen causing cutaneous infections (zygomycosis) following the use of Elastoplast bandages to cover surgical wounds. Although the term mucormycosis has often been used for this syndrome, zygomycosis is now the preferred term for this angio-invasive disease. Rhizopus arrhizus is the most common cause of zygomycosis and is followed by Rhizopus microsporus var. rhizopodiformis.
