abstract = {During surveys of dying vegetation in natural ecosystems and associated waterways in Australia many
new taxa have been identified from Phytophthora ITS Clade 6. For representative isolates, the region spanning the
internal transcribed spacer region of the ribosomal DNA, the nuclear gene encoding heat shock protein 90 and the
mitochondrial cox1 gene were PCR amplified and sequenced. Based on phylogenetic analysis and morphological
and physiological comparison, four species and one informally designated taxon have been described; Phytophthora
gibbosa, P. gregata, P. litoralis, P. thermophila and P. taxon paludosa. Phytophthora gibbosa, P. gregata and P. taxon
paludosa form a new cluster and share a common ancestor; they are homothallic and generally associated with
dying vegetation in swampy or water-logged areas. Phytophthora thermophila and P. litoralis are sister species to
each other and more distantly to P. gonapodyides. Both new species are common in waterways and cause scattered
mortality within native vegetation. They are self-sterile and appear well adapted for survival in an aquatic
environment and inundated soils, filling the niche occupied by P. gonapodyides and P. taxon salixsoil in the northern
hemisphere. Currently the origin of these new taxa, their pathogenicity and their role in natural ecosystems are
unknown. Following the precautionary principle, they should be regarded as a potential threat to native ecosystems
and managed to minimise their further spread}
