Characters: Colonies are compact clumps or bushes. Branches are fine, upright, tapered and irregularly fused (caespitose). Branchlets develop from incipient axial corallites and are evenly spaced. Axial corallites are small, although well defined. Radial corallites are tubular and appressed with small openings (less than 1 mm diameter).
Colour: Uniform yellow, cream or blue (which may photograph pink).
Similar species: Acropora cerealis, which has much larger branches and corallites. See also A. parilis also A. subulata.
