| Description： |
Mycelium extensive, moderately dense; principal hyphae stout; branched; 50-110 μ in diameterat base. Gemmae very abundant, filiform or irregular occasionally branched; usually intercalary and catenulate, rarely single. Zoosporangia not abundant; filiform, fusiform; in general 300 × 45 μ; renewed sympodially. Zoospore discharge achlyoid; spore cluster not persistentat exit pore. Encysted spore 10 μ in diameter. Oogonia abundant; lateral, not intercalary;spherical, rarely pyriform; 40-66 μ in diameter, predominantly 50-60 μ; immature ones frequently proliferating. Oogonial wall pitted; smooth; occasionally irregular on inner surface.Oogonial stalks 1-3? times the diameter of the oogonium in length, generally 1-2 times; stout;often curved or bent, rarely coiled once. Antheridial branches diclinous, infrequently monoclinous,with a remote origin; usually coiling about hyphae which may or may not bear oogonia,but losing feature as colony ages; irregular, much branched; wrapping about or not wrappingabout the oogonium. Antheridial cell tubular, clasping the oogonium; attached by projections,rarely laterally appressed. Fertilization tube not observed. Oospheres frequently not maturing. Oospores eccentric; spherical or ellipsoidal; usually not filling the oogonium; 1-12in number, generally 4-9; 17.5-31.5 μ in diameter, predominantly 20-24 μ. | |||
