MycoKeys 27: 39–64. https://doi.org/10.3897/mycokeys.27.14866 Abstract The genusHydnophlebia includes two species of wood-inhabiting fungi, Hydnophlebia chrysorhizon and Hydnophlebia omnivora. Both are characterized by cream to reddish-orange, resupinate basidiome, with hydnoid hymenophore, margin with strands, a monomitic hyphal system, tubular to ventricose cystidia and elliptical spores. In this paper, a taxonomic study of Hydnophlebia, using morphology and molecular analyses of large subunit nuclear ribosomal DNA (LSU) and the internal transcribed spacer nrDNA op- eron (ITS), is reported. Three new species, Hydnophlebia canariensis, H. gorgonea and H. meloi, from the Macaronesia bioregion (Canary Islands and Cape Verde Archipelago), are described. Keywords Agaricomycetes, corticioid fungi, phylogeny, taxonomy, Canary Islands, Cape Verde Archipelago Introduction Hydnophlebia was erected by Parmasto (1967) to accommodate Hydnum chrysorhi- zon Torr. A few years later, the type species was transferred to Phanerochaete P. Karst.
