Maximum recorded size: 35 cm across. Corallites are immersed with distinct, steeply sloping acutely ridged walls whose ridges can appear pale, giving the colony a honeycomb-like appearance. Corallite size 3.0 mm in diameter. Colours range from yellowish to shades of light and dark brown. Goniastrea appears similar, but has highly visible septa that give the colony walls a serrated appearance, with colonies coloured more pale brown-whitish, rather than the uniform brown of Gardineroseris (Fig. 78 ).
