The Generic Circumscription of Kockiozyma (Lipomycetaceae)

Abstract: 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 in the genus Myxozyma. This paper deals with the phylogenetic relationships between the teleomorphic 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 among the species in the 18S rRNA gene sequences. Thus, the following seven Myxozyma species were accommodated to the genus Kockiozyma as Kockiozyma geophila f.a., Kockiozyma sirexii f.a., Kockiozyma neotropica f.a., Kockiozyma vanderwaltii f.a., Kockiozyma mucilagina f.a., Kockiozyma neglecta f.a. and Kockiozyma melibiosi f.a. Keywords: Kockiozyma suomiensis; Myxozyma geophila; Kockiozyma geophila f.a.; Kockiozyma melibiosi f.a.; Zygozyma oligophaga.
