Abstract

Two strains (NYNU 121010 and NYNU 121032) of a novel basidiomycetous yeast species belonging to the genus were isolated from insect frass collected from trunks of a pagoda tree ( L.) in Yantai, Shandong province, east China. The sequence analyses of the D1/D2 domain of the large subunit (LSU) rRNA gene and the internal transcribed spacer (ITS) region indicated that the closest relatives were FIRDI 007, CBS 7429 and sp. S6A. The D1/D2 sequences of the novel strains differed by 12 nt substitutions (2 %) from the type strain of . , and by 13 nt substitutions (2.2 %) from the type strain of . and from sp. S6A. The novel strains differed from closely related species by more than 4.6 % substitutions in the ITS region. The novel strains can also be distinguished from . and . on the basis of a number of morphological and physiological characteristics and represent a novel species in the genus , for which the name sp. nov. is proposed. The type strain is NYNU 121010 ( = CICC 32998 = CBS 12813). The Mycobank deposit number is MB 804119.
