Bayesian inference tree based on ITS sequence data 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). Isolates designated as P. alticola in CBS correspond to P. palmivora (purple) and P. frigida (orange). The posterior probability is shown at the nodes. Phytophthora castaneae and P. heaveae were used as outgroup taxa. Asterisks indicate the re-sequenced isolates CBS 121937 and CBS 121938. CBS 121939 was resequenced, but not included as it was identical to the sequence on q-bank for this isolate.
