DESCRIPTION
Turbinate, patellate or subcylindrical solitary coral with calice elliptical to subcircular in outline. Flattened calicular platform, more or less infundibuliform, with a generally deep fossa at the axis. Rejuvenescences are common in the coralla. Radial elements are straight, free or joined, subcompact costosepta with flat granule-like pennulae on lateral faces. Pennulae do not alternate between neighbouring septa and are not arranged in continuous meniana. The distal edge is ornamented of strong teeth. More the teeth are in the axial region bigger and more detached they are. They produce in the center the appearance of a papillose columella in a pit. Numerous thick dissepiments. Synapticulae present. Wall parathecal. A thin epitheca, sometimes totally eroded wraps the coralla. Probable hexameral symmetry.
Calicular diameter: 13 to 29.5 mm – Number of septa: 119 to 182 – Septal density: 4 to 6 for 2 mm.
SIMILARITIES AND DIFFERENCES
Differs from P.multiradiata Beauvais, 1986 ,which shows a convex calicinal surface with exert septa and a more discoid morphology.
