Name and publication
Phytophthora litoralis Jung, Stukely & Burgess (2011)
Jung T, Stukely MJC, Hardy GE St, White MD, Paap T, Dunstan WA, and Burgess TI. 2011. Multiple new Phytophthora species from ITS Clade 6 associated with natural ecosystems in Australia: evolutionary and ecological implications. Persoonia 13: 13–39.
from Jung et al (2011)
referred to as P. sp. 11 by Burgess et al. (2009)
refers to the frequent association of this species with coastal and riparian vegetation and the littoral zone of water bodies

Position in ITS phylogenetic tree
Colonies and cardinal temperatures
Colony morphology is uniform on V8A, stellate with sparse aerial mycelium on CA; petaloid, appressed to submerged colonies on MEA; and irregular and dense-felty on PDA. Minimum growth temperature 10°C, optimum 30°C and maximum 35°C.
Conditions for growth and sporulation
Sporangia are nonpapillate, persistent, ovoid to elongated ovoid or limoniform with average dimensions of 43.6 ± 7.7 × 29.4 ± 5.4 μm (overall range 27.8–76.9 × 16.0–40.4 μm). Sporangiophores in simple sympodia and internal proliferation, both nested and extended, occurs in chains. External proliferation leading to lax sympodia is also observed. Hyphal swellings are globose, angular or irregular-elongated and often catenulate. Chlamydospores globose, 34.3 ± 5.3 μm.
Sterile in culture.
Most typical characters
Phytophthora litoralis is in a species cluster with Phytophthora amnicola, Phytophthora fluvialis, Phytophthora moyootj, and Phytophthora thermophila, all recovered from waterways in Western Australia. They all have similar morphological features.
