Penicillium citrinum

A slow-growing fungus that produces a blue-green colony with a bright yellow reverse, within fourteen days, when incubated at 25oC (77oF). It is a common fungus isolated worldwide from soil, plants, bird feathers, gerbils, flour-based food-stuffs, and fruit juices. Rarely, it can be an opportunistic human pathogen causing eye (corneal ulcers) infections.
