- Oogonium coronulate, subspherical, of medium size, averaging from 0.7 mm to 0.8 mm in height, width equal to or slightly greater than height, greatest transverse diameter at or just below midheight. Base truncate or gently rounded, summit deeply truncate. Ridges intercellular, ten, completing between a fourth to a half turn around the oogonium, equatorial angle 30° to 35°. The ridges are of uniform width from base to summit, narrow, each with a slight median groove. Cellular furrows deep and narrow. Coronula cells ten, deeply concave on outer surface, corresponding in position with the cellular furrows and forming an erect to sub-erect parapetlike ring around the summit orifice, the inner surface of the coronula ring constituting a narrow funnel to the opening. Oospore membrane unknown.
