sp. nov., an ascomycetous yeast isolated from Tibet Free

Abstract

Eight apiculate strains isolated from Tibet, PR China, were identified as and a novel species of based on the sequence analysis of the ITS region, the D1/D2 domains of the LSU rRNA and the translation elongation factor 1-a () gene. Among them, four strains with identical sequences of D1/D2 and ITS formed a separate branch from the known species in the phylogenetic trees, and differed from the known species by at least 17 (3 %) nucleotide (nt) substitutions in the D1/D2 domains and more than 6 % substitutions and inserts/deletes in the ITS region. The phylogenetic analysis indicated that those four strains represent a novel species of , for which the names sp. nov. (holotype CGMCC 2.6175; MycoBank MB 834591) is proposed. The other four strains belonging to produce spherical, void or fusiform ascospores, which differ from the original description that ascospores are absent.
