Extract from Wikipedia article: Phyllotopsis nidulans, commonly known as the mock oyster or the orange oyster, is a species of fungus in the family Tricholomataceae, and the type species of the genus Phyllotopsis. It is widely dispersed in temperate zones of the Northern Hemisphere, where it grows on decaying wood. The fungus fruit body consists of a fan-shaped, light orange fuzzy cap up to 8 cm (3 in) wide that grows singly or in overlapping clusters. On the cap underside are crowded orange gills. Mock oyster mushrooms have a strong, unpleasant odor, although they are not known to be poisonous.
