Morphological identification
Colonies and cardinal temperatures
Colony morphology on V8, PDA, MEA, and CA are woolly and uniform. Growth is fast on all media. Minimum growth temperature 4°C, optimum 32.5°C, maximum greater than 37.5°C.
Conditions for growth and sporulation
Sporangia are produced in water cultures (soil extract or river water) and not observed in solid media. Oogonia are not observed in single culture or when paired with tester strains.
Asexual phase
Sporangia are nonpapillate, persistent, exclusively ovoid to elongated ovoid with average dimensions of 63.3 ± 8.3 x 39.7 ± 5.8 µm (overall range 40.9–75.7 x 21.2–51.1 µm). Sporangiophores are simple, and internal proliferation both nested and extended occurred in chains. Hyphal swellings absent. Chlamydospores absent.
Sexual phase
Sterile in culture.
Most typical characters
The most typical features for Phytophthora balyanboodja are its uniform sporangia proliferating in chains, as well as its fast growth rate and high temperature optima.
