Three methanol-utilizing yeast strains were isolated from basidiocarps of Ganoderma sp. collected from a tree trunk in Mangshan Mountain, Hunan Province, southern China. These strains formed hat-shaped ascospores in unconjugated and deliquescent asci. Sequence analysis of the large-subunit rRNA gene D1/D2 domain and internal transcribed spacer (ITS) region, electrophoretic karyotype comparison and phenotypic characterization demonstrated that the three strains represent a novel species of the genus Ogataea, which is described as Ogataea ganodermae sp. nov. (type strain SHS 2.1T =CGMCC AS 2.3435T =CBS 10646T). Phylogenetically, the novel species was closely related to Ogataea pini and Ogataea henricii. The latter two taxa with similar D1/D2 sequences were confirmed to represent separate species by ITS sequence and electrophoretic karyotype comparisons.
The GenBank/EMBL/DDBJ accession number for the 26S rRNA gene D1/D2 domain sequence of strain SHS 2.1T is EU117201; those for the ITS region sequences of strains CBS 744T and SHS 2.1T are EU117199 and EU117202, respectively.
