The genus Kockiozyma was introduced as the ninth and the monotypic genus in the family Lipomycetaceae. On the other hand, a number of anamorphic species were reported as Myxozyma. This paper deals with the phylogenetic relationships between the teleomor-phic species, Kockiozyma suomiensis and the anamorphic species. To constitute a taxonomic-homogeneous natured genus, 1) the several species concerned have to be tightly coupled with one another phylogenetically. 2) To make the several species tightly coupled, the branch lengths have to be short or the calculated sequence similarities have to be 98% or more in the 18S rRNA gene sequences among the species. Thus, the following seven Myxozyma species were accommodated to the genus Kockiozyma as Kockiozyma geophila f.a., Kockiozyma sirexiif.a., Kockiozyma neotropica f.a., Kockiozyma vander-waltii f.a., Kockiozyma mucilagina f.a., Kockiozyma neglecta f.a. and Kockiozyma melibiosi f.a.
