Abstract

The new methanol-assimilating yeast species Kurtzman sp. nov. (type strain NRRL Y-7556=CBS 2612) is described. Of the four known strains of this species, two were isolated from black oak trees in California, USA, one from an Emory oak in Arizona, USA, and one from an unidentified source in Mexico. The species forms hat-shaped ascospores in deliquescent asci and appears to be homothallic. Analysis of nucleotide sequences from domains D1/D2 of large-subunit (26S) rDNA separates the new species from , the type species of the genus, and from , which is here renamed (Dlauchy, Tornai-Lehoczki, Fülöp & Péter) Kurtzman comb. nov. (type strain NRRL Y-27603=CBS 9187=NCAIM Y 01541). On the basis of D1/D2 26S rDNA sequence analysis, the three species now assigned to the genus represent a clade that is phylogenetically isolated from other ascomycetous yeast genera.
