Figure – Phylogram generated from maximum likelihood analysis based on combined LSU,
SSU and rpb2 sequence data of selected taxa from Falcocladiales and Torpedosporales. Twenty-six
strains are included in the combined gene analyses comprising 3557 characters after alignment
(1142 characters for LSU, 1440 characters for SSU and 967 characters for rpb2). Nectria
haematococca (GJS89-70) is used as the outgroup taxon. Analyses of each single gene were
performed and the topology of each tree had clade stability. The tree topology in maximum
likelihood analysis was similar to the Bayesian and maximum parsimony analyses. Maximum
likelihood analysis with 1000 bootstrap replicates yielded a best tree with the likelihood value of –
14936.746257. The matrix had 1096 distinct alignment patterns, with 25.55% of undetermined
characters or gaps. Estimated base frequencies were as follows; A = 0.247642, C = 0.231060, G =
0.304405, T = 0.216894; substitution rates AC = 1.746605, AG = 3.110551, AT = 1.540183, CG =
1.746965, CT = 7.476678, GT = 1.000000; gamma distribution shape parameter α = 0.291342.
Maximum parsimony (black) and maximum likelihood (black) bootstrap values >65% and
Bayesian posterior probabilities (blue) >0.90 (ML/BYPP) are given above the nodes. Ex-type
strains are in bold.
