Phylogram generated from maximum likelihood analysis based on combined LSU and ITS sequence data. Twenty-two taxa were included in the combined analyses, which comprised 1393 characters (LSU = 844 bp and ITS = 549 bp) after alignment. The best scoring RAxML tree with a final likelihood value of -4677.993509 is presented. The matrix had 336 distinct alignment patterns, with 9.65% of undetermined characters or gaps. Estimated base frequencies were as follows: A = 0.243499, C = 0.247400, G = 0.289966, T = 0.219136; substitution rates: AC = 3.067252, AG = 2.397685, AT = 1.551875, CG = 1.069828, CT = 6.624253, GT = 1.000000; gamma distribution shape parameter α = 0.240919. 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 Periconia byssoides (H 4600), P. digitata (CBS 510.77) and P. pseudodigitata (KT 1395). The strain numbers are noted after the species names with ex-type strains indicated by T. The newly generated sequences are indicated in blue.
