Rickiopora is a fungal genus of unknown familial placement in the order Polyporales.
[4] In collaboration with Mauro Westphalen and Michal Tomšovský, Rajchenberg circumscribed the new genus Rickiopora in 2016 to contain the fungus.
[2] The fungus Antrodiella angulatopora, described from Venezuela by Leif Ryvarden in 1987, was later determined by Rajchenberg to be synonymous with Ceriporiopsis latemarginata.
The hyphal system is monomitic, consisting of clamped and metachromatic generative hyphae (staining a reddish purple when mounted in cresyl blue), and thick-walled hyphae with sparse clamps.
Rickiopora features both a bipolar mating system, and astatocenocytic nuclear behaviour.
