Two novel yeast strains, NYNU 236247 and NYNU 23523, were isolated from the leaves of Hance, collected in the Tianchi Mountain National Forest Park, Henan Province, central China. Phylogenetic analysis of the D1/D2 domain of the large subunit rRNA gene and the internal transcribed spacer (ITS) region revealed the closest relatives of the strains are three described species: , and . The novel species differed from the type strains of these three species by 12 to 22 nucleotide substitutions and 1 gap (~2.

Four strains (NYNU 178247, NYNU 178251, DMKU-PAL160 and DMKU-PAL137) representing a novel yeast species were isolated from the external surfaces of rice and pineapple leaves collected in China and Thailand. Phylogenetic analysis based on the concatenated sequences of the internal transcribed spacer (ITS) regions and the D1/D2 domains of the large subunit rRNA gene revealed that the novel species belonged to the genus . The D1/D2 sequence of the novel species differed from its closest relative, SYSU-17, by 3.
