| Author： |
Rhizophydium elyensis Sparrow, Trans. Brit. mycol. Soc. 40:525. 1957. |

| Description： |
On pine pollen: Sporangium epibiotic or interbiotic, spherical, 20-45 μm diam., ovate or ellipsoid, 20 m 27-22.5 25 μm. Zoospores globose, about 5 μm diam. Rhizoidal system extensive, up to 250 μm, with branches reaching several pollen grains. On 1/4YpSs agar: Immature sporangia spherical, subspherical or ovoid; mature sporangia becoming irregularly polygonal, 30-65 I 77.5 μm diam.; wall smooth, with 1-12 exit papillae filled with a spherical plug. Main rhizoidal axis tubular, 3.2-7 μm diam., branched and extensive up to 112.5-212.5 μm. Zoospores globose, 3-3.5 μm diam., often emerging from several papillae simultaneously in an amoeboid manner, then darting away. Color of colony white to offwhite. | |||

| Note： |
The sporangium has several exit papillae which are filled with a spherical plug. When mature, the sporangium becomes irregularly polygonal. The above character is similar to Sparrow‘s (1957) and Karling’s (1967a) descriptions. This species has been reported by Konno (1984), but our isolate is the only strain obtained in pure culture. | |||
