Diagnosis

Reference	Diagnosis
C. W. Merriam 1972	Trochoid, turbinate, and ceratoid rugose corals with shallow to moderately deep conical calice. Internal tissue predominantly dissepimental; septa, if present, represented by radially alined, slender, mostly short trabecular spines extending inward and upward from convex distal surfaces of dissepiments and tabulae. Tabularium commonly not sharply differentiated from dissepimentarium; wide near-horizontal tabulae absent in mature growth stages.
