Maximum likelihood tree of Stenotrophomyces fumitolerans WT5 sp. nov. and related species and genera of the family Saccharomycetaceae with outgroup taxa from families Debaryomycetaceae, Phaffomycetaceae and Pichiaceae obtained from the combined analysis of SSU, 5.8S rRNA, LSU, TEF1 and RPB2 genes. The tree is rooted with sequences of Schizosaccharomyces pombe. The numbers provided on branches are frequencies (>50%) with which a given branch appeared in 100 through bootstrap replications. The scale bars indicate the numbers of expected substitutions accumulated per site. Accession numbers of nucleotide sequences are provided in Supplementary Table S1.
