Monocentric calices are 6-13 mm diameter. Calices are fairly rounded and thick walled, but a varied and even a high proportion of calices are di- or tri-stomodaeal. Mature calices are up to 10 mm deep and have a well formed columella. There are two orders of septa, though the thinner, second order also usually reach the columella. Septa of adjacent septa may meet, though usually there is a groove separating calices. Septal spines are large and thick. It forms nearly perfectly domed and spherical colonies up to 60 cm diameter, which also makes it conspicuous. Although this is a clear species, it has previously been regarded as a monocentric to tristomodaeal Acanthastrea.
