| Description： |
Mycelium extensive. Zoospore discharge achlyoid. Gemmae filiform, or irregular; abundant.Oogonia abundant; lateral; 42.5-97 μ in diameter predominantly 50-70 μ. Oogonial wall usually unpitted. Oogonial stalk straight, sometimes curved. Antheridial branch monoclinous rarely androgynous. Oospheres maturing. Oospores eccentric; spherical; not filling the oogonium; 1-12 in number generally 4-7 in the oogonium; 22.5-45 μ in diameter, generally 25-27.5 μ. | |||

| Note： |
Our isolate is remarkably close to Achlya americana, a species which was established fundamentally on the basis of pitted oogonia and many oospores in the oogonium as contrasted with unpitted oogonia and fewer oospores of our isolate. And it is much like Achlya klebsiana with unpitted nature of oogonial walls in both species. But A. klebsiana established on the basis of the diclinous and the remotely originating monoclinous antheridial branches, is different from the monoclinous and androgynous antheridial branches of our isolate. In fact, our isolate more close to Achlya cambrica; but the former without “Pseudopapillate” oogoium. We believed our isolate as Achlya debaryana on the basis of the monoclinous and androgynous antheridial branch, unpitted oognial wall, maturing oospore and without “Pseudopapillate” oogonium. | |||
