49; see text Ceriporia is a widely distributed genus of crust fungi.

The genus was circumscribed by Dutch mycologist Marinus Anton Donk in 1930, with Ceriporia viridans as the type species.

[3] Molecular phylogenetic analyses have shown that Ceriporia is not monophyletic,[4][5] despite an earlier study which suggested the contrary.

[6] The presence or absence of cystidia is not considered a phylogenetic character in delimiting the species of Ceriporia.

[4] Although traditionally classified in the family Phanerochaetaceae,[7] recent molecular phylogenetic analysis supports the placement of Ceriporia in the Irpicaceae.
