Position in ITS phylogenetic tree
Colonies and cardinal temperatures
Colony morphology is stellate with limited aerial mycelium on V8 agar, rosaceous on carrot agar, and growth on potato-dextrose agar is very slow. Minimum growth temperature 7.5°C, optimum 25–32.5°C, and maximum 37.5°C.
Conditions for growth and sporulation
Sporangia are nonpapillate, persistent, ovoid, or limoniform with average dimensions of 62 ± 9.0 × 35.3 ± 5.6 μm (overall range 39–78 × 17–43 μm). Sporangiophores in simple sympodia and internal proliferation, both nested and extended, occur in chains. Hyphal swellings are ellipsoid to irregular, catenulate occurring in clusters. Chlamydospores absent
Sterile in culture.
Most typical characters
Phytophthora amnicola is in a species cluster with Phytophthora litoralis, Phytophthora fluvialis, Phytophthora moyootj, and Phytophthora thermophila, all recovered from waterways in Western Australia. There are few features to distinguish these species, however P. amnicola is the only species that produces rosaceous colonies on CA.
