Radial elements are free or joined, often wavy septa of fluctuating width with inner edge generally swollen. In most of the calices, the first cycles of septa are so enlarged that they link together into a ring that more or less completely encloses the lumen and separate it from the interseptal chambers. There are at least 3 distinct size orders of septa in the septal apparatus. Endotheca made of tabular dissepiments and wall probably parathecal. An epitheca s.l. wraps the corallites. Calicular diameter: 3.3 to 7.3 mm – Distance between calices: 7 to 13 mm – Number of septa: approximately 60 to 70 – Septal density: 8 per 2 mm .
