¹ cal: partial calmodulin gene; his3: partial histone H3 gene; ITS: partial cluster of nrRNA genes, including the nuclear 5.8S rRNA gene and its flanking internally transcribed spacer regions ITS1 and ITS2; tef1: partial translation elongation factor 1-alpha gene; tub2: partial beta-tubulin gene; ² 5-loci: combined dataset based on ITS, tef1, tub2, cal and his3 loci; 4-loci: combined dataset based on ITS, tef1, tub2 and cal loci; 3-loci: combined dataset based on ITS, tef1 and tub2 loci; N/A: not applicable, locus excluded from the dataset; * Positive for recombination, PHI test yielded a p < 0.05.
