a Maximum likelihood phylogenetic tree, based on concatenated seven gene sequences (ITS, LSU, SSU, CYTB, RPB1, RPB2, TEF1), extracted from WGS of the respective type strains (superscript T) or from the available genomes, showing the phylogenetic relationship of C. onofrii with closely related members of Cystobasidiomycetes. The gene fragment lengths in base pairs are as given in Fig. 2. Bootstrap values from 1000 replications are shown at branch points. Bar = 0.1 substitution per site. GenBank accession numbers of the sequences are listed in Additional file 1: Table S2. b WGS Maximum likelihood phylogeny of Cystobasidium onofrii reconstructed using a concatenated alignment of universally distributed yeast genes. Branch fidelity used two different approaches, Ultrafast bootstraps and Gene Concordance Factors, which were added next to its corresponding branches
