DESCRIPTION: Hyphae 1.5-7 µm in diam. Sporangia elongated, often branched, 80-170 µm in diam., germinate producing zoospores. Cysts 5-8 µm in diam. Oogonia terminal, intercalary, lateral, spherical, 14-24 µm in diam., smooth-walled. Antheridia monoclinal or diclinal, 1-2 per oogonium, antheridial cell club-shaped, attached to the oogonium by its apex. Oospore pleurotic with a smooth wall, 1-2 µm thick.
