Ceriporia purpurea  Ceriporia purpurea is a species of crust fungus in the family Irpicaceae. It was first described by Swedish mycologist Elias Magnus Fries in 1821 as "Polyporus purpureus". Marinus Anton Donk gave the fungus its current name when he transferred it to the genus "Ceriporia" in 1971. A 2016 study identified six similar "Ceriporia" species, referred to as the "Ceriporia purpurea" group: "Ceriporia bresadolae", the European species "C. torpida" and "C. triumphalis", and the North American species "C. manzanitae" and "C. occidentalis". "Ceriporia purpurea" is widely distributed in the temperate zone of Eurasia, where it grows exclusively on the decomposing wood of deciduous trees, and also in the American North-East.
