A phylogenetic analysis of and related taxa is proposed, based on a wide sampling of temperate and tropical species. Concatenate sequences of ribosomal DNA (ITS1-5.8S-ITS2) and RPB2 gene from mycelia cultures were analyzed by Maximum Likelihood and Bayesian methods, whilst morphological features were documented from the corresponding herbarium vouchers. Congruent results were obtained from analyses of ribosomal LSU sequences downloaded from Genbank. The Bayesian analysis of ITS + RPB2 sequences gave the best resolution for the phylogenetic reconstructions and revealed the existence of three main lineages in the -clade: 1) a monospecific lineage represented by 2) a lineage including the genus in its traditional sense and several species usually classified in the genus (, , , ) & 3) a lineage corresponding to the core genus , including type species of , and . The presence of a pseudostipe, aspect and structure of the abhymenial surface, colour change with 5% aqueous solutions of potassium hydroxide and topography of pigments on skeletal hyphae gave relevant morphological support to these clades. When the structure of the hymenial surface, presence of a black line below the tomentum and color of context (except for genus ) usually used in traditional polypore-classifications did not reveal any phylogenetic significance. A partial systematic arrangement of the clade is proposed, with the introduction of a new genus: Welti & Courtec. .. Two new combinations: (Berk.) Welti & Courtec. . and (Berk.) Welti & Courtec. . are proposed.
