supports: 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. 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. Heliocybe is an agaric genus closely allied to "Neolentinus" and the bracket fungus, "Gloeophyllum", all of which cause brown rot of wood. Heliocybe sulcata, the type and sole species, is characterized by thumb-sized, tough, revivable, often dried, mushroom fruitbodies, with a tanned symmetric pileus that is radially cracked into a cartoon sun-like pattern of arranged scales and ridges, distant serrated lamellae, and a scaly central stipe. Microscopically it differs from "Neolentinus" by the absence of clamp connections. Like "Neolentinus", it produces abundant, conspicuous pleurocystidia. "Heliocybe sulcata" typically fruits on decorticated, sun-dried and cracked wood, such as fence posts and rails, vineyard trellises in Europe, branches in slash areas, and semi-arid areas such on sagebrush or on naio branches in rain shadow areas of Hawaii, or in open pine forests. Neolentinus is a genus of wood-decaying agarics with tough (leathery to woody) fruit bodies composed of dimitic tissue, serrated lamella edges, and nonamyloid white binucleate basidiospores among other features. It was segregated from "Lentinus" in the broad taxonomic sense, hence the derivation of the name. Biologically "Neolentinus" species produce a brown rot type of decay of wood, whereas "Lentinus" causes a white rot. Molecular phylogenetic analysis shows that the two genera are unrelated. "Neolentinus" is phylogenetically allied to other brown rot genera such as "Gloeophyllum", "Heliocybe", and "Veluticeps". A new order, the Gloeophyllales, has been described for these fungi. "Heliocybe" had been placed in synonymy but it differs phylogenetically and anatomically by the lack of clamp connections that all "Neolentinus" produce on their generative hyphae. Neolentinus lepideus is a basidiomycete mushroom of the genus Neolentinus , until recently also widely known as Lentinus lepideus . Common names for it include scaly lentinus and train wrecker .
