Position in ITS phylogenetic tree
Colonies and cardinal temperatures
Cultures on V8-A and PDA with no distinctive pattern and on MEA with light stellate pattern. Minimum temperature for growth 9°C, optimum 24°C, maximum 27°C.
Conditions for growth and sporulation
Sporangia papillate, persistent or caducous with short to medium pedicel up to 10 µm long, with variable shapes including ovoid to obpyriform, ellipsoid, irregular (mainly asymetrical in shape) (27–66 L x 20–49 W µm), often with elongated necks and formed frequently laterally on the stalk; originated in simple sympodial sporangiophores. Hyphal swellings globose to subglobose, found in sporulating water cultures. Chlamydospores absent.
Homothallic. Oogonia spherical with broadly funnel shape (tapering base) (25–35 x 28–32 µm); antheridia amphigynous, spherical, ellipsoid or ovoid (small 7–13 µm), and occasionally with one or more short spines; oospores aplerotic, wall 3 µm thick.
Most typical characters
Phytophthora heveae is characterized by the presence of oogonia with broadly funnel shape (tapering base).
