| Description： |
Mycelium limited diffuse, principal hyphae slender; average 50 μ in diameter. Gemmae moderately abundant; filiform. Oogonia very abundant; spherical or pyriform; 40-76 μ in diameter. Oogonial wall smooth; pitted only under point of attachment of antheridial cells, rarely at other places, or unpitted. Oogonial stalk 1-6 times the diameter of the oogonium in length, generally 1-3 times; straight, infrequently bent or curved. Antheridial branches diclinous, occasionally to extremely rarely monoclinous. Antheridial cell tubular or clavate, occasionally irregular; attached by short or long projections. Fertilization tube not observed. Oospheres maturing. Oospores eccentric; spherical occasionally ellipsoid; generally filling the oogonium; 1-15 in number predominantly 2-8; 20-35 μ in diameter predominantly 20-25 μ. Germination of oospore not observed. | |||

| Note： |
A. klebsiana in Taiwan is easily accessed from wet soils. The mature oospores are plerotic. Antheridia usually are diclinous or monoclinous, rarely anhydrogynous. The monoclinous antheridium trait owned by A. klebsiana implicated an close affinity with A. debaryana. Although In general the pit ornamation on oogonium is absent, it exists in some isolates. | |||
