Phylograms obtained from ML analysis of ITS sequences A and β-tubulin sequences B of Graphilbum showing fungal associates with pines infected by Tomicus yunnanensis and T. minor in Yunnan Province, China. Novel sequences obtained in this study are printed in bold type. Bootstrap values ≥ 70% for ML and MP are indicated above branches. Bootstrap values < 70% are indicated by the symbol *. Strains representing ex-type sequences are marked with ‘T’; ML, maximum likelihood; MP, maximum parsimony and the final alignment of 515 (A), 481 (B) positions, including gaps.
