Remarks (public):Parmasto (1967) described Byssomerulius to include some species with simple-septate generative hyphae and merulioid hymenophore with Thelephora corium Pers. as generic type species; Meruliopsis Bondartsev, was described to include Xylomyzon taxicola Pers., with a typical poroid hymenophore (Parmasto 1959). Byssomerulius, Candelabrochaete, Ceriporia, Gloeoporus, and Meruliopsis, all sharing generative simple-septate hyphae, are classified by molecular data in the Byssomerulius family, with other clamped species as Phlebia nitidula and Ceraceomyces serpens (Larsson 2007b).
