Euglypha cuspidata

Euglypha cuspidata

Euglypha cuspidata  Bonnet, 1959

Diagnosis: Shell small, very transparent, ovoid, in lateral view very elliptical, with sharp edges. Pseudostome small, elliptical, surrounded by a small number of apertural plates (6-8) resembling those of E. rotunda Wailes, but with relatively long median tooth, bordered by two projections. Shell built of elliptical plates, 4×2 µm, the longitudinal row much more accentuated than the transversal one, and without any order at the fundus.

Dimensions: Length 30-35 µm, width 18-22 µm, thickness 8-10 µm, pseudostome 8×6 µm.

Ecology: Very common species in all soils high in humic matter, in particular in brown forest soils.
