Cotylidia

Cotylidia is a fungal genus characterized by small to moderately sized, white to palely yet brightly colored, stalked, fan-shaped to funnel-shaped fruitbodies with a smooth to wrinkled hymenium, tissues composed of monomitic hyphae, basidia producing smooth, nonamyloid spores, the absence of clamp connections, and bearing projectng cylindrical, thin-walled, hymenial cystidia. The genus is classified in the Hymenochaetales , however the type species, C. undulata has not yet been sequenced molecularly using DNA. Phylogenetically related agaricoid fungi to the two species of Cotylidia thus far sequenced are in the genera Rickenella, Contumyces, Gyroflexus, Loreleia, Cantharellopsis and Blasiphalia, and Cyphellostereum  and the clavaroid genus, Alloclavaria.

The ecological status of Cotylidia remains unresolved. They fruit on soil or plant debris, sometimes on burn sites or among bryophytes. The culture characteristics are unknown.
