Phylogram generated from maximum likelihood analysis based on combined ITS, tef1-α and rpb2 sequence data. Seventy-eight taxa were included in the combined analyses, which comprised 1920 characters (ITS = 583 bp, tef1-α = 512 bp and rpb2 = 825 bp) after alignment. The best scoring RAxML tree with a final likelihood value of -22800.405782 is presented. The matrix had 983 distinct alignment patterns, with 25.05% of undetermined characters or gaps. Estimated base frequencies were as follows: A = 0.260557, C = 0.263561, G = 0.230377, T = 0.245504; substitution rates: AC = 1.414531, AG = 3.978691, AT = 1.319991, CG = 0.945884, CT = 6.618473, GT = 1.000000; gamma distribution shape parameter α = 0.262034. Bootstrap support values for ML equal to or greater than 60% and prior probabilities (PPs) equal to or greater than 0.95 are given above the nodes as ML/PP. The tree was rooted to Dactylellina copepodii (CBS 487.90) and D. cangshanensis (CGMCC 3.19714). The strain numbers are noted after the species names with ex-type strains indicated by T. The newly generated sequences are indicated in blue.
