- Diagnosis
- Oogonium spherical to elongate spherical, large, averaging about 1.0 mm in height, greatest transverse diameter at or just below mid-height, equal to or slightly less than height. Base gently rounded to slightly truncate, summit truncate. Grouped around a small, somewhat depressed basal opening are nine shallow pits that branch into eighteen meridional rows of about twelve pits extending from the point of origin to the comparatively large, funnel-shaped summit opening. Pits in adjoining rows hexagonal in shape and alternating or rectangular and in lateral alignment, commonly both arrangements evident on a single specimen. Oospore membrane contracted, usually extending as an elongate spheroid from summit opening to basal opening, sometimes folded, occasionally in contact with oogonium wall.
