New systematic position of Aurantiporus alborubescens (Meruliaceae, Basidiomycota), a threatened old-growth forest polypore

Original Article


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–rpb1rpb2) 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.

This work is dedicated to the memory of the excellent French mycologist, Hubert Bourdot, on the 80th anniversary of the death. We thank Dr. Bart Buyck (curator of PC) for arranging the loan of the type and other specimens of Phaeolus alborubescens. The technical support of Pertti Salo and Dr. Otto Miettinen (Botanical Museum, University of Helsinki) is acknowledged as well. The following colleagues are thanked for supporting our work: Dr. Daniel Dvořák (Masaryk University, Brno) for valuable discussions, Attila Koszka for providing us with the Hungarian specimen of Odoria alborubescens and his in situ photos of the basidiomata, Dr. Dániel G. Knapp (Eötvös Loránd University, Budapest) for valuable advice during the laboratory process, and Dr. Gábor M. Kovács (Eötvös Loránd University, Budapest) for the financial support of the molecular study. We are very grateful to Dr. Joseph Ammirati for his linguistic improvements on the manuscript.
