Phytophthora pluvialis is a semi-papillate plant pathogen that mainly infects tanoak-Douglas-fir forests of western Oregon.

[2] 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.

Sporangia formed in water are ovoid and slightly irregular, semi-papillate, terminal or subterminal, and partially caducous with medium-sized pedicels.
