Abstract Phylogenetic relationships among those yeast species that form saturn-shaped ascospores and which are assigned to the generaWilliopsis andPichia were estimated from their extent of nucleotide sequence divergence in three regions of ribosomal RNA. ThePichia species (P. dispora, P. saitoi, P. zaruensis andP. sp. nov.) are a closely clustered group only distantly related toWilliopsis, and it is proposed that they be reassigned toSaturnospora gen. nov. The extent of divergence amongWilliopsis species (W. californica, W. mucosa, W. pratensis, W. saturnus andW. sp. nov.) is greater than that previously observed within other ascomycetous yeast genera.
