Description Solitary corallum with a hexagonal star-shaped outline and a very high calicular relief. No epitheca but thick costae. Radial elements are compact anastomosed, unequal, straight or slightly curved costosepta. Lateral faces ornamented with opposite carinae. No pali. Microstructure unknown but the ornamentation of septa suggest a montlivaltid microstructure. Clear hexameral (G. angulata) or pentameral (Duncan created G. leckenbyi for this) symmetry with thick S1 (the branches of the star) on which other septa are symmetrically and regularly anastomosed. Endotheca present with dissepiments, the central zone seems to be occupied by a fossa, synapticulae absent, The wall is an intercostal paratheca limited at the base of the corallum. [details]

Description Solitary corallum with a hexagonal star-shaped outline and a very high calicular relief. No epitheca but thick costae. Radial elements are compact anastomosed, unequal, straight or slightly curved costosepta. Lateral faces ornamented with opposite carinae. No pali. Microstructure unknown but the ornamentation of septa suggest a montlivaltid microstructure. Clear hexameral (G. angulata) or pentameral (Duncan created G. leckenbyi for this) symmetry with thick S1 (the branches of the star) on which other septa are symmetrically and regularly anastomosed. Endotheca present with dissepiments, the central zone seems to be occupied by a fossa, synapticulae absent, The wall is an intercostal paratheca limited at the base of the corallum. [details]Remark The synapticulae described by Duncan are interpreted as the section of dissepiments. Two nominal species known from the same locality. Gonioseris was potentially an automobile coral. See also Dimorphosmilia. [details]
