Penicillium purpurogenum

A slow-growing fungus that produces a deep yellow-green colony with a deep red to dark reddish-purple reverse, within seven days, when incubated at 25oC (77oF). It produces a dark red to dark-reddish purple diffusible pigment and a fruity (apples or walnuts) odor. It has a worldwide distribution and has been isolated from soil, mangrove swamps, sandy soil, desert soil, polluted water, plants, bird feathers, leather, and optical lenses. There have not been any reports of human infections.
