abstract = {Isolates belonging to a novel Phytophthora species were frequently recovered during an oak forest-soil survey of Phytophthora species in eastern and north central US in 2004. The species was isolated using an oak leaf baiting method from rhizosphere soil samples collected from Quercus rubra, Q. macrocarpa and Q. phellos. This species is formally designated as P. quercetorum. It is homothallic and has aplerotic oogonia and paragynous antheridia. It produces papillate sporangia (occasionally bipapillate) of ovoid-elongated shapes. Its temperature optimum for growth is ca. 22.5 ?C with the upper limit of ca. 32.5 ?C. P. quercetorum differs from the morphologically related P. quercina, in producing distinct submerged colony-patterns, different growth-temperature requirements, and oogonial shapes and sizes. Phylogenetic analyses using seven nuclear loci supported P. quercetorum as a novel species within Clade 4, closely related to P. arecae, P. palmivora, P. megakarya, and P. quercina. P. quercetorum was pathogenic to root and stem tissues of various oak species when inoculated artificially.}
