DESCRIPTION

Solitary discoid corallum.Epitheca weakly folded covering a little more than half of the basal face.Calice circular in outline.Radial elements are prominent, compact, straight costo-septa. Distal edge ornamented by some regular wide festoons corresponding to the variations in thickness. No pali but some detached columns. Hexameral symmetry easy to decipher especially with the external part of radial elements. Endotheca not observed. Columella formed by teeth fused to inner edges of S1 septa; other cycles show free septa. Wall parathecal or septothecal.

Calicular diameter: 21.8 mm – Number of septa: approximately 50.

SIMILARITIES AND DIFFERENCES
