Phylogenetic tree of the genus Ovatospora constructed from ITS, LSU, tub2 and rpb2. Notes: Statistical support values (BI/ML) were shown at nodes. ML bootstrap values ≥ 75% and posterior probabilities ≥ 0.90 are shown above the internal branches. ‘–’ indicates the absence of statistical support (< 75% for bootstrap proportions from ML analysis; < 0.90 for posterior probabilities from Bayesian analysis). Three new strains are shown in blue.
