Molecular phylogeny of Trametes and related genera

Mitochondrial small subunit ribosomal DNAs were sequenced and phylogenetica lly analyzed for Trametes and related genera of Ryvarden's Trametes group. Parsimony and distance analyses indicated that most of trimitic genera with white rotting habit of the Trametes group clustered within a single clade, suggesting that they may have originated from a common ancestor. The phylo genetic position and generic placement of Trametes consors was uncertain as yet. Trametes trogii grouped with Coriolopsis gallica and indicated that c olor of the basidiocarp is a poor character at generic level. Nucleotide di fferences between Daedaleopsis confragosa and D. tricolor were quite few an d both species closely grouped together in a same clade, thus supporting th at D. tricolor might be an ecotype of D. confragosa.
