Synonymy of Metschnikowia pulcherrima and Torulopsis burgeffiana

Torulopsis burgeffiana is placed in the genus Metschnikowia because it has been shown to have a perfect stage corresponding with this genus. Due to the characteristic shape of the ascus and ascospores, T. burgeffiana is to be considered a synonym of M. pulcherrima. The physiological differences which exist between strains are not sufficiently important to maintain a separate species.
