Phytophthora pluvialis is homothallic; it forms oogonia in culture. Its oogonia are terminal, smooth and globose, being approximately 30 µm in diameter, and possess amphigynous antheridia. Its oospores are globose and aplerotic, being about 28 µm in diameter. Sporangia formed in water are ovoid and slightly irregular, semi-papillate, terminal or subterminal, and partially caducous with medium-sized pedicels.
