Phylogram obtained from Maximum Likelihood (ML) analyses of the ITS2-28S for selected species of Leptographium sensu lato. Sequences obtained during this study are presented in bold type. The Bootstrap values ≥ 75% for ML and Maximum Parsimony (MP) analyses are presented at nodes as follows: ML/MP. Bold branches indicate posterior probabilities values ≥ 0.95 obtained from Bayesian Inference (BI) analyses. * Bootstrap values <75%. The tree is drawn to scale (see bar) with branch length measured in the number of substitutions per site. Ophiostoma karelicum and O. quercus represents the outgroup in analyses of ITS2-28S.
