Axial corallites : Outer diameter 2.8–3.6 mm ; inner diameter 0.9–1.2 mm ; tubular with thick wall; blade-like septa are present in two neat cycles. Radial corallites : Uniformly sized and arranged; nariform with extending and thickened outer wall that can be slightly hooked; opening is very elongate or dimidiate; septa are dentate but rudimentary. Coenosteum : Costate or broken costae on and between radial corallites. Remarks: A. cerealis has a resemblance to A. nasuta (Dana, 1846), but Wallace and Wolstenholme (1998) differentiate them by A. cerealis having thinner branches and radial corallites with more extended outer-wall, sometimes hooked upwards. Our diagnosis is mainly based on these two features as well as the different coenosteum structure. As noted by Veron and Wallace (1984) , A. cerealis also has a more branching growth pattern than A. nasuta , which was also the case here.
