Figure 13 – Phylogram generated from maximum likelihood analysis based on combined ITS,
LSU, rpb2 and tef1 sequence data of Distoseptisporales and Sporidesmiales. Forty-six strains are
included in the combined analyses which comprised 3153 characters (789 characters for LSU, 546
characters for ITS, 1038 characters for rpb2, 779 characters for tef1) after alignment. Single gene
analyses were carried out and the phylogenies were similar in topology and clade stability. Tree
topology of the maximum likelihood analysis is similar to the Bayesian analysis. The best RaxML
tree with a final likelihood value of -22582.382236 is presented. Estimated base frequencies were
as follows: A = 0.236961, C = 0.261709, G = 0.291323, T = 0.210007; substitution rates AC =
1.206796, AG = 2.260744, AT = 1.272906, CG = 1.049687, CT = 6.479176, GT = 1.000000;
gamma distribution shape parameter a = 0.651156. Bootstrap support values for ML greater than
75% and Bayesian posterior probabilities greater than 0.95 are given near the nodes. The tree is
rooted with Sordaria fimicola (FGSC 2918 and SMH 4106). Ex-type strains are in bold. The newly
generated sequences are indicated in blue.
