Four new species in Lipomyces

For new species in Lipomyces are described. In terms of nuclear genome comparison the genus Lipomyces comprises three species-clusters. A key to the nine species now assigned to the genus, is given. The delimitation of species by (i) rRNA nucleotide sequence analyses of the 18S and 25S subunits and (II) nDNA homology determinations, do not invariably lead to the recognition of congruent taxa. The family of the Lipomycetaceae, nevertheless provides an illuminative model for phylogenetic studies in terms of more appropriate ribosomal nucleotide sequence analyses of both its teleomorphic and anamorphic members.
