Rhizopus oryzae 
Fast growing and a colony can grow all over the agar plate in 4 days. The colony is first white, but then turns gray and finally yellowish-brown. The structure is cotton candy-like.

Humans with weakened immune defenceMucoromycosisThe symptoms depend on where in the body the infection takes place, but hyphae grow into the blood vessels around the area of infection (angioinvasion). Angioinvasion leads to thrombosis and necrosis in the infected area.
