Cochliobolus species

A rapidly-growing fungus that produces a dark brown colony with a dark reverse, within five days, when incubated at 25oC (77oF). The hyphae, conidiophores, and conidia are pigmented olivaceous-brown (dematiaceous). It is found worldwide and is very common. It can be isolated from the air, plants, and soil. Rarely, it can be an opportunistic human pathogen causing eye (corneal) infections, mycetoma, and infections in immunocompromised patients.
