Diagnosis. “Polyps small, usually 0.5–1.0 mm in transverse diameter; subequal in transverse and sagittal axes or slightly longer along either axis; interpolypar space often relatively wide, as much as 0.4 mm in preserved material. Tentacles of polyps in preserved material short and blunt. Spines tall ( 0.4 mm or more), acicular to cylindrical, and anisomorphic; maximum height usually more than three times the width near the base; acute or blunt, smooth or slightly tuberculate on parts of surface, especially near the apex. Polypar spines considerably taller than abpolypar spines; circumpolypar spines larger than interpolypar spines; hypostomal spines usually reduced or absent. Corallum flabellate or bushy. Stem and branches simple or pinnulate. When present, pinnules simple” ( Opresko, 2004).
