Veluticeps

Veluticeps is a small genus of wood-rot fungi characterized by the production of resupinate to bracket shaped, perennial, tough, brown fruitbodies, that blacken when KOH solution is applied, and with a smooth to warted or cracked fertile undersurface. They cause a brown rot of wood.[1] Cystidia in the hymenium are characteristically mostly in fascicles. The genus may be monotypic if Columnocystis is excluded. Phylogenetically, the type species, V. berkeleyi, groups with several other brown rot genera such as Neolentinus, Heliocybe, and Gloeophyllum....read more on Wikipedia.
