Description:
Valves weakly clavate to linear-lanceolate with shortly protracted, rounded head poles and sharply narrowed foot poles (L 20-27µm, W 4-5,5µm, 14-18 striae in 10µm). Axial area narrow, linear. Central area unilaterally elongated due to one shortened stria in the middle. Stigma present next to the non-shortened stria in the middle. Raphe straight, filiform with unmarked central pores. Transapical striae almost parallel to weakly radiate, more radiate towards the head poles. Areolae not resolvable in LM.

Autecology:
Notes:
Locally common on Ile de la Possession in wet mosses and circumneutral lakes and brooklets. No clear ecological preferences.South Georgia (Van de Vijver & Beyens 1996). Other records are lacking, probably due to confusion with G. parvulum which is very widespread in the area.
