Phylograms obtained from ML analysis of ITS2-28S A β-tubulin B and elongation factor C sequences of Leptographium, showing fungal associates with pines infected by Tomicus yunnanensis and T. brevipilosus 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 641 (A), 358 (B), 639 (C) positions, including gaps.
