Roniewicz, 1989: 132
Type Species
Coccophyllum acanthophorum Frech 1890: 89, pl. 20, fig. 4-11; Monotypy Roniewicz, 1989: 132
Type Specimen: Syntype; GBA No. 2272; Verified; Dry Preserved
Type Locality: Fischerwiese, Northern Calcareous Alps, Zlambach Beds, Rhaetian.

Classification
Diagnosis
Cerioid; wall septothecal; septa nonconfluent or subconfluent, made of thin septal spines arranged into a half-fan: peripheral spines vertical and remaining inclined axialwards; septal sides smooth; distal septal granulation and denticulation of the internal septal border are regular; dissepiments large, convex or subhorizontal; budding intercalicular. Microstructure: skeletal fibres organized into separate fascicles each forming individual septal spine.
Description
Frech 1890: 89 well described morphology of the type species. First description and illustrations of microstructural features was given by Cuif, 1973: 280,fig.32. The type species was redescribed, and its status redefined by Roniewicz 1989:133, pl.41,fig.5-7.
Comparisons
From Coccophyllum it differs in having septal spines arranged in a half-fan and dissepimental endotheca, while in Coccophyllum the spines are subhorizontal and endotheca is tabular.
Remarks
Only the type species is well documented; determination of corals from America attributed to the species needs comparison with type material.
