- Oogonium depressed spherical, large, averaging about 0.9 mm in height, wider than high, greatest transverse diameter at mid-height averaging about 1.2 mm. Base and summit deeply truncate. Extending from the small basal opening to the slightly larger summit opening are sixteen meridional ridges separated by wide shallow furrows. Equally spaced on the ridges and in lateral alignment are fifteen or sixteen small tubercles. The tubercles are connected laterally by faint lines dividing the furrows into fifteen or sixteen shallow rectangular pits. Oospore unknown.
