Phylogenetic tree generated from maximum likelihood (ML) analysis based on combined LSU and ITS sequence data for the species from Chaetosphaeriales. Related sequences are taken from Lin et al. [64]. One-hundred three taxa were included in the combined analyses which comprised 1329 characters after alignment including gaps. LSU: 789 bp, ITS: 540 bp. The RAxML analysis of the combined dataset yielded a best scoring tree with a final ML optimization likelihood value of −19,119.372669. The matrix had 730 distinct alignment patterns, with 13.78% undetermined characters or gaps. Estimated base frequencies were as follows: A = 0.225668, C = 0.269306, G = 0.309464, T = 0.195562; substitution rates AC = 1.438984, AG = 1.899345, AT = 1.390083, CG = 0.832127, CT = 6.028381, GT = 1.000000; gamma distribution shape parameter α = 0.286425. Bootstrap support values for ML equal to or greater than 75% and BYPP equal to or greater than 0.95 are given above the nodes. Neurospora tetraspora (CBS 178.33) and Sordaria fimicola (CBS 508.50) from Sordariales were used as outgroup taxa. The newly generated sequence is indicated in blue. The ex-type strains are indicated in bold.
