Figure 3. Biogeographic and ancestral analyses. A.Inference of the historical biogeography of Ostreobium spp. using Bayesian binary MCMC analysis (BBM) in RASP v. 3.0. Colors of pie wedges at each node represent geographical areas inferred to have been occupied by ancestral taxa. B. Mesquite Parsimony ancestral state mapping suggesting the host for ancestors of Ostreobium spp. Samples. The color of the branches represents the genera of the ancestral host, some branches have two colors that represent the uncertainly about the inferred host. The red labels in both cases represent the new sequences of this study.
