  1. Apex narrowed, rounded and/or subrostrate
  2. Striae radiate
  3. Raphe valve with asymmetric stauros

Valves of Lemnicola are linear to linear-elliptical. The valve apices may be narrowed, rounded, or subrostrate. The striae are slightly radial throughout and composed of biseriate rows of circular areolae. The raphe valve has an asymmetrical stauros.

Lemnicola was erected for a single species, Lemnicola hungarica (Grun.) Round et Basson, which had previously been considered within Achnanthidium or Achnanthes. Living cells have single, plate-like plastids. Cells grow as epiphytes on the aquatic angiosperms Lemna and Wolfia.
