Phylogenetic re-evaluation of Trametes consors based on mitochondrial small subunit ribosomal DNA sequences

Mitochondrial small subunit ribosomal DNAs of Cerrena unicolor and Trametes consors were sequenced and compared with those of known mushroom taxa. Tra metes consors is a species recently transferred from Irpex, and Cerrena is a genus closely related to Trametes. The present phylogenetic tree showed t hat Cerrena unicolor and Trametes consors clustered together and made an in dependent lineage from the Trametes group. A new combination, Cerrena conso rs (Berk.) Ko and Jung, comb. nov., is proposed here by transferring Tramet es consors into Cerrena based on molecular data along with taxonomic eviden ce.
