Phyllotopsis nidulans, commonly known as the mock oyster or the orange oyster, is a species of fungus in the family Phyllotopsidaceae.

The fungus fruit body consists of a fan-shaped, light orange fuzzy cap up to 10 cm (4 in) wide that grows singly or in overlapping clusters. On the cap underside are crowded orange gills. Mock oyster mushrooms have an unpleasant odor and are regarded as inedible.

It is widely dispersed in temperate zones of the Northern Hemisphere, where it grows on decaying wood.
