Bipolaris spicifera

A rapidly-growing fungus that produces a grayish-brown to black colony, within seven days when incubated at 25oC (77oF). It is found worldwide and is commonly isolated from soil, sand, plants, birds, and cotton fabrics. It can produce the mycotoxin sterigmatocystin which can cause liver and kidney damage in humans and animals. Rarely it is an opportunistic human pathogen.
