Description Phaceloid corallum with subcylindrical corallites covered with an epitheca showing regular growth rings and finer striation. costae. Corallite outline subcircular to distorted after the intracalicular budding, cutting calicular edge. Radial elements compact, free, attenuated, straight. Distal edge with regular teeth, inner edge with detached trabeculae producing a papillose columella, lateral faces possibly with mi-pennules, Microstructure not known. Hexameral symmetry probable, bilateral symmetry poorly developed. Endotheca made of dissepiments straightened near the wall and sloping down to the center, columella papillose, peripheric wall whose the nature is difficult to precise. Very small vertical striation suggesting a trabecular nature. [details]

Comparison Thecactinastraea differs from Phacelophyllia because of its free septa.
