Genus Ceriporia Donk

Mededelingen van het botanisch Museum en Herbarium van de Rijksuniversiteit Utrecht 9: 170 (1933)

Type: Polyporus viridans Berk. & Broome, Annals and Magazine of Natural History 7: 380 (1861)

This resupinate poroid genus seems defined by simple characters and what it lacks. The genus is characterized by a monomitic hyphal system with simple septate generative hyphae, hyaline spores, lack of cystidia, and a white rot in the attacked wood. It may be looked upon as a counterpart to Ceriporiopsis which is separated in principle only by clamped generative hyphae. From page 180 in Ryvarden and Gilbertson, 1993, European polypores. Part 1. Synopsis Fungorum. 6:1-387.

Two species are identified from Chicago. There are about seven other species in North America, but some may fall outside of Ceriporia in the strict sense since the genus is polyphyletic.

  1. Ceriporia purpurea, pore surface purple; one historic record.
  2. Ceriporia spissa, bright orange to reddish-brown; only recent records.
