Four yeast strains were isolated from soil in a mixed deciduous forest in Amphoe Wang Nam Khiao, Nakhon Ratchasima province, Thailand. On the basis of morphological, biochemical, physiological and chemotaxonomic characteristics, and the sequence analyses of the D1/D2 domain of the large‐subunit (LSU) rRNA gene, small‐subunit rRNA gene and internal transcribed spacer (ITS) region, the three strains (S‐29, S‐63 and S‐80) were found to represent a single species of the genus Wickerhamomyces , which were named Wickerhamomyces edaphicus sp. nov. The type strain is S‐29 T (BCC 21231 T =NBRC 101969 T =CBS 10408 T ). Strain S‐75 represented a novel species of the genus Pichia on the basis of morphological, biochemical, physiological and chemotaxonomic characteristics, and the sequence analyses of the D1/D2 domain of the LSU rRNA gene, for which the name Pichia jaroonii sp. nov. is proposed. The type strain is S‐75 T (BCC 23061 T , NRBC 102180 T =CBS 10930 T ).
