Sixty-two isolates among the 65 yeast strains isolated from Jiangxi province, China, were identified into 15 known species based on the sequence analysis of the D1/D2 domains of the LSU rRNA and ITS region. The other three strains, GaoanZ14, GaoanC57, and GaoanC191, isolated from tea-oil fruits, were identified as two undescribed species of Phaeotremella based on the multiple gene sequence analysis, physiological, and biochemical comparisons. Strains GaoanC57 and GaoanC191 had one substitution difference both in the D1/D2 domains of the LSU rRNA and ITS region. They formed a separate branch from the other Phaeotremella species in the D1/D2 and multiple genes trees, and differed from the known species by at least 10 nucleotide substitutions in the D1/D2 domains and more than 6% mismatches in the ITS region. The phylogenetic analysis indicated that those two strains represent a novel species of Phaeotremella, for which the names Phaeotremella camelliae sp. nov. (Holotype CGMCC 2.6141, Mycobank MB832699) is proposed. Only one strain, GaoanZ14, represents the other undescribed species of Phaeotremella, so it will be described in latter when more strains are found.
