Bayesian inference tree based on concatenated sequence data from ITS, β-tubulin, HSP90, enolase and coxI gene regions generated in MrBayes using the GTR +G substitution model showing relationship between P. alticola nom. dub. (green), P. boodjera sp. nov. (blue) and P. arenaria (red). The posterior probability is shown at the nodes. Phytophthora castaneae and P. heaveae were used as outgroup taxa.
