Phylograms obtained from ML analysis of β-tubulin A and elongation factor B sequences of Esteya, showing fungal associates with pines infected by Tomicus yunnanensis 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 320 (A), 856 (B) positions, including gaps.
