Description Massive meandroid corallum with corallites in series produced by intratentacular increase or isolated corallites....
Description Massive meandroid corallum with corallites in series produced by intratentacular increase or isolated corallites. Externally covered by a granulated tectura. Highly variable collines: tectiform, tholiform or depressed. If present, the peritheca is narrow. Radial elements are compact, free, straight, bicuneiform costosepta. They are alternately thick and thin. Inner edge of primary septa with T-form enlargements, tertiary septa attenuated. Apophysal septa and lonsdaleoid septa exist. No palis. Rhipidogyrid microstructure. Strong bilateral symmetry. Endotheca present. Columella lamellar, synapticulae absent but tigella possibly present in depth between primary septa and the columella. Wall probably septoparathecal and thickened in stereozone. [details]

Comparison Very close of Psammogyra, which has a smooth wide peritheca. Placogyra has also shorter series.
