DESCRIPTION

The test is discoidal with calcareous wall and its diameter varies between 0.55-1.89 mm. It is dimorphic and there are chambers in megalospheric forms with trochospiral whorls after the proloculus. The following chambers are irregularly arranged in different sizes. As it is clearly seen in well-oriented sections, the connection between chambers is provided by the basal stolons.
