- Diagnosis
- Sporangia thick-walled and flattened in the plane of the substratum, circular, 8-22 ,u diam, to irregularly elliptical, up to as much as 22 ,u long. Sporangia more or less deeply lobed, the lobes being separated by distinctive narrow invaginations, many of which have a characteristic circular enlargement at the proximal ends. In larger sporangia these invaginations commonly occur in radial sets of two or three lengths, each shorter invagination being between two next longer invaginations. Sporangia smooth or papillate, some having the persistent thickened zoospore cyst, 2.5-3.5 ,u diam, and germ-tube. Many have a clearly defined, circular exit pore, 2-2.5 ,u diam. Zoospores and rhizoidal axes unknown
