| Description： |
On pine pollen: Sporangium epibiotic or interbiotic, spherical 25-45 μm, fusiform, or ovoid, 25-35 × 37.5-45 μm, the apex prolonged into a short beak or a long tube, with gelatinous plug in the apical region. Rhizoids frequently from one to two, sometimes several, arising from the lower part of the sporangium, branched or unbranched, extending to several pollens. Resting spore spherical. On 1/4YpSs agar: Sporangium spherical or subspherical, 20-150 μm, with 1-5 exit papillae, 12.5-22.5 μm in diameter. Rhizoids arising from three to several parts of the sporangium base. Zoospores spherical, 4-5 μm in diameter, with a flagellum, 15-25 μm long; some zoospores larger, 7.5-12.5 μm, with 2-4 flagella; with a large refractive globule; emerging in a spherical vesicle, soon becoming active and swim away, also amoeboid. Resting spore not observed. Color of colony white to buff. | |||

| Note： |
Sporangial shape on 1/4YpSs agar is different from that in 1/4YpSs slush and on pine pollen. Sporangial size is variable. Resting spores occasionally observed in our isolates on pine pollen. | |||
