Colonies and cardinal temperatures

Colony morphology petaloid in PYGs culture medium. Optimum growth temperature 30°C and maximum 35°C.

Asexual phase

Sporangia nonpapillated or semipapillate; persistent; ovoid to obpyriform (35–58 μm long x 20–45 μm wide); basal plug present; internal (nested and extended) proliferation; sporangia produced in unbranched sporangiophores. Hyphal swellings spherical, globose, tubular, obpyriform to irregular shape. Chlamydospores absent.

NOTE: Additional vesicle in sporangia has not been observed in Phytophthora.
