Phylograms obtained from analyses of ITS sequence data, revealing the identity of ophiostomatoid fungi isolated from H. abietis infesting pine forests in Poland. Phylograms of partial β-tubulin data are shown for species groups where ITS sequences did not resolve the identity of Polish isolates. The β-tubulin data sets were analysed separately from each other because of differences among the three groups in the presence and absence of introns 3, 4 and 5. Sequences obtained during this study are presented in bold type. All phylograms presented were obtained from maximum likelihood (ML) analyses. Bootstrap values >75 % for ML and posterior probabilities >75 % obtained from Bayesian (BI) analyses are presented at nodes as follows: ML/BI
