Abstract

The genus Wickerhamomyces Kurtzman et al. (2008) was extremely diverse phylogenetically, since a large number of species were equipped with long branches. Of the genus, Wickerhamomyces anomalus (= Hansenula anomala) and the remaining eight species mutually produced a large cluster with short branches. The pair-wise sequence similarities of H. anomala were very high (96.5-99.1%) to the eight species. Thus, the genus Hansenula Sydow et Sydow (1919) was revived as a taxonomic homogeneous-natured taxon and phylogenetically and taxonomically separated from the genus Wickerhamomyces. In addition, the genus Wickerhamomyces was designated as the double generic-structured, along with the genus Lipomyces sensu Kurtzman et al. (as the multiple generic-structured) and the genus Schizosaccharomyces sensu Kurtzman et Robnett (as the quadruple generic-structured). The three genera actually corresponded respectively to a higher-ranked taxon, i.e., the family.
