Phlebia radiata, commonly known as the wrinkled crust, is a common species of crust fungus in the family Meripilaceae. It is widespread in the Northern Hemisphere. It grows as a wrinkled, orange to pinkish waxy crust on the decaying wood of coniferous and deciduous trees, in which it causes a white rot. The fungus was first described scientifically in 1821 by Elias Magnus Fries.
