Description
Summary:Odoria (Meruliaceae, Basidiomycota) is described as a new genus established for the threatened old-growth forest polypore Phaeolus alborubescens that was previously discussed in Aurantiporus or Tyromyces . It is characterized by the annual pinkish white spongy basidiocarp with strong sweetish smell, turning pale brown when drying, and has a positive reaction with KOH solution, the lack of cystidia, and the monomitic hyphal system with clamped generative hyphae often covered with fine orange crystals. Multigene phylogenetic analyses based on a combined (5.8S–nucLSU– rpb1 – rpb2 ) and a single locus (nrITS) dataset place Odoria in Meruliaceae (Phlebioid clade), close to Crustodontia , Sarcodontia , Luteoporia , and Phlebiporia . Molecular as well as anatomical study of the old type specimen of P. alborubescens is also provided.
