Classification
Description
Solitary trochoid corallum. Calice subircular moderately deep. Radial elements are compact, free, straight to slightly curved costosepta. Slightly bicuneiform to attenuated, major septa having their inner edge thickened. Ornamentation difficult to observe on the lectotype due to a strong silicification. Symmetry radial and bilateral marked by the torsion of septa and the elongated fossa. Endotheca with vesicular dissepiments regularly sloping to the center. Exotheca with dissepiments that do not cover the costae. No columella. Parathecal wall.
Comparisons
