FIG. 2.

Combined maximum likelihood analysis of six genes (ACT1, EF2, RPB1, RPB2, 18S rDNA, and 26S rDNA) for 38 taxa of Hemiascomycetes and two outgroup species, an Archiascomycete (S. pombe) and a Euascomycete (N. crassa). Thickened lines denote heterogeneous Bayesian posterior probabilities ≥95% as calculated in the combined analysis. Node numbers are indicated above each branch. Refer to Table 4 for the statistical support of each node by each gene, as well as the combined multigenic support. Branch lengths leading to Y. lipolytica (0.19157) and the outgroup taxa (0.31967) were shortened to fit the figure. Black lines on the right indicate the three clades recognized in this study.
