On pine pollen: Sporangium epibiotic, occasionally interbiotic, may be spherical, slightly flattened, and oval, with one to three exit papillae. The spherical ones vary from 15-25 μm in diameter. Zoospores oval and tapering as they are emerging from the sporangia; after they have been swimming for some times, they become spherical, 2.5-4 μm in diameter, with a 15-25 μm long flagellum.
On 1/4 YpSs agar: Sporangium spherical, papillae one to three; the knob and peg-like structure beneath the sporangium; extremely fine, delicate thread-like branched rhizoids at the tip of the haustorium. Color of colony distinctly yellow.
