Diagnosis: Test hemispherical, brownish, thin, chitinous, covered with small flat mineral particles; pseudostome slightly invaginated, aperture about half the test diameter.

Dimensions: Diameter 100-110 µm.

Ecology: Freshwater, Sphagnum, submerged mosses. Probably cosmopolite.

Remarks: Van Oye (1951) describes a variety minima with a diameter of 40 µm.
