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. Trametes consors is a species recently transferred from Irpex, and Cerrena is a genus closely related to Trametes. The present phylogenetic tree showed that Cerrena unicolor and Trametes consors clustered together and made an independent lineage from the Trametes group. A new combination, Cerrena consors (Berk.) Ko and Jung, comb nov., is proposed here by transferring Trametes consors into Cerrena based on molecular data along with taxonomic evidence.
