Phylogenetic relationships and species boundaries of C. siamense s. lat. and related species. Fifty percent majority rule consensus tree from a Bayesian analysis based on a six-locus combined dataset (ApMat, CAL, GAPDH, GS, ITS, TUB2). Posterior probabilities (PP, > 0.95) are displayed at the nodes. Thickened branches indicate branches also present in the ML tree with > 50 % bootstrap support values. Bars in the first column at the right present the results of the phylogenetic analysis based on five-locus (CAL, GAPDH, GS, ITS, TUB2) alignment, respectively. The other three columns present the results of three coalescent-based species delimitation methods (GMYC, PTP, BPP). “A” and “B” represent the two potential species inferred from PTP analysis. Ex-type cultures are emphasized in bold. Stars indicate isolates included in the mating test
