Colonies and cardinal temperatures

Colony with scanty aerial mycelium and no defined growth pattern in PYGs culture medium. Optimum growth temperature 30°C and maximum 35°C.

Sporangia nonpapillated or semipapillate; persistent; ovoid to obpyriform, elongate (55–83 μm long x 43–63 μm wide); producing internal (nested and extended) proliferation; produced in unbranched or simple sympodial sporangiophores; sporangia presenting additional vesicle. Hyphal swellings globose, tubular, or with lobate shape. Chlamydospores absent.

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