Figure 2 Maximum clade creditability tree of Laboulbenia isolates reconstructed from an LSU dataset, with L. bruchii as outgroup. The topology is the result of Bayesian inference performed with BEAST. For each node, ML BS (≥ 65) and Bayesian pp (≥ 0.7) are presented above/below the branch leading to that node. Isolates are color-coded by host; L. quarantenae sp. nov. is highlighted with gray shading.
