Abstract

A novel ascomycetous yeast, designated strain N7a-Y2, was isolated from soil collected in a potato field in Ochang, Korea, and its taxonomic position was studied. A neighbour-joining tree based on the D1/D2 domain of large-subunit rRNA gene sequences revealed that the isolate was a member of the clade and that it was closely related to , , and . Strain N7a-Y2 formed Saturn-shaped ascospores in unconjugated and persistent asci. D1/D2 domain 26S rRNA gene sequence divergences of 11.0–21.1 % between strain N7a-Y2 and other members of the clade indicate that the strain represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is N7a-Y2 ( = KCTC 17870  = CBS 11843).
