Contumyces

Contumyces is a genus of brightly colored possibly bryophilous or graminicolous agarics in the Hymenochaetales. They have an omphalinoid morphology, and therefore were previously classified in Omphalina. They inhabit mossy or grassy silty or sandy soils in the Northern Hemisphere. Phylogenetically related agarics are in the genera Rickenella, Gyroflexus, Loreleia, Cantharellopsis and Blasiphalia, as well as the stipitate-stereoid genera Muscinupta and Cotylidia and clavarioid genus, Alloclavaria. Contumyces is most similar to Rickenella and Blasiphalia and differs by having its cystidia on the cap, stipe, and hymenium in clusters, whereas in Rickenella and Blasiphalia the cystidia are solitary. Lichenomphalia also may appear similar, but grows on mossy wood.
