Difflugia brychtai   Stepanek, 1967

Diagnosis: Test pyriform. Fundus with a long thick spike located not on the longitudinal axis of the test, because of which the form of the test appears to be irregular. Covered with large mineral grains. Pseudostome round.

Dimensions: Length 81 µm, width 46 µm, pseudostome 24 µm.

Ecology: Freshwater. Europe.

Remarks: In my opinion, this species is synonymous with D. mammilaris.
