Figure 8 – Phylogram generated from maximum likelihood analysis based on combined LSU and
ITS sequence data of Chaetosphaeriales and Tracyllalales taxa. Ninety-six strains are included in
the combined analyses which comprised 1695 characters (1081 characters for LSU, 614 characters
for ITS) after alignment. Neurospora crassa MUCL 19026 and Gelasinospora tetrasperma CBS
178.33 (Sordariaceae, Sordariales) are used as outgroup taxa. 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 – 23777.689886 is presented. Estimated base frequencies were as follows: A = 0.231060, C
= 0.264793, G = 0.308265, T = 0.195882; substitution rates AC = 1.388486, AG = 1.836207, AT =
1.649563, CG = 0.971659, CT = 6.316962, GT = 1.000000; gamma distribution shape parameter a
= 0.460297. Bootstrap support values for ML greater than 75% and Bayesian posterior probabilities
greater than 0.95 are given near the nodes. Ex-type strains are in bold. The newly generated
sequences are indicated in blue.
