| Description： |
On pine pollen: Sporangium epibiotic or interbiotic, spherical, 10-30 μm diam., or pyriform; wall smooth, with 2-6 papillae. Rhizoidal system arising from a single point, usually with one subsporangial swelling. Zoospores oval, 2.5-3 μm diam., emerging away from the pores of sporangium. On 1/4YpSs agar: Sporangium spherical, 12.5-37.5 μm diam., or suboval, 25-30 μm diam., rarely fusiform, 22.5 y 30 μm, with 3-12 papillae or discharge tube, 5-20 μm in length. Rhizoidal system developed from one, frequently several, unbranched or branched apophysis. Zoospores globose, 3-4 μm diam., swimming away individually from discharge pores, movement hopping. Resting spore resembling the sporangium, 17.5-30 μm diam., but with long papillae, 15-20 μm in length, frequently sickle-shaped; upon germinating the papillae deliquence and discharge zoospores. Color of colony chrimic yellow. | |||

| Note： |
This species frequently has a branched apophysis. The very long, sickle-shaped, discharge tubes on the resting spore is the main character for this species. | |||
