Strain DMKU13-2 T , representing a novel anamorphic yeast species in the class Microbotryomycetes, subphylum Puccinomycotina, phylum Basidiomycota, was isolated from a soft coral collected in the sea off Ko Mu island, Thailand. The phylogenetic analysis based on the concatenated sequences of the internal transcribed spacer (ITS) region and the D1/D2 region of the large subunit ribosomal RNA (LSU rRNA) gene indicated that this strain was a novel species in the genus Spencerozyma and distant from Spencerozyma crocea, the only species of the genus. The novel species differed from the type of S. crocea (CBS 2029 T ) by 5.2 % nucleotides (31 nucleotide substitutions out of 594 bp) in the D1/D2 region of the LSU rRNA gene and 9.0 % nucleotides (66 nucleotide substitutions out of 735 bp) in the ITS region. The name Spencerozyma siamensis sp. nov. is proposed. The type is DMKU13-2 T (=CBS 14683=TBRC 7039). The MycoBank number is MB 824889.
