Cotylidia
Cotylidia is a fungal genus characterized by small to moderately sized, white to palely  yet brightly colored, stalked, fan-shaped to funnel-shaped fruit bodies  with a smooth to wrinkled hymenium, tissues composed of monomitic hyphae, basidia producing smooth, nonamyloid spores, the absence of clamp connections, and bearing projecting cylindrical, thin-walled, hymenial cystidia. The genus is classified in the Hymenochaetales, however the type species, C. undulata has not yet been sequenced. 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  Muscinupta and the clavarioid 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. Etymology

The generic name is derived from Greek and means "small cup" in reference to the fluted glass shape. Species
