A novel ascomycetous yeast was isolated from flowers of Lilium sp. and Ipomoea sp. in Korea. The name Metschnikowia koreensis sp. nov. (type strain SG99-34T = CBS 8854T = KCTC 7998T) is proposed for this novel species based on comparative sequence analyses of the D1/D2 domain of 26S rDNA and phenotypic characteristics.
