Russula velenovskyi new to Japan, with phylogenetic implications of Russula species between Japanese subalpine forests and Northern Europe

Publication date: July 2018Source: Mycoscience, Volume 59, Issue 4Author(s): Yoshito Shimono, Taiga Kasuya, Susumu TakamatsuAbstractTo compare morphological characters and phylogenetic placement between Japanese and European Russula, 32 specimens of 12 species were collected from Japanese subalpine forests and Northern Europe. Several sequences of nrDNA ITS region (ITS) of these Russula species were obtained. High homological similarities were shown between ITS sequences of several Russula samples collected from Japanese subalpine forests, Europe and North America. These facts show distribution of the same Russula species among these areas. From morphological observations and phylogenetic analyses, two same Russula species, R. velenovskyi, and R. decolorans are found in Japan, Europe and North America. Of these, R. velenovskyi collected from Mt. Fuji, Mt. Nyukasa and Mt. Tateshina in mountainous area of central Honshu is reported as a new Japanese record.
