Corallum morphology in Agariciidae (according to Wood. 1983)
Genus Form and size of colony Calice arrangement Walls/collines Septal and septocostal arrangements and features
Pavona Great variation in growth form and colony size. Round, oval or elongate polygonal; 2-3mm in diameter. Walls lacking or present; collines may enclose several calices. Septa narrow, continuous b/w centers; margins smooth or with very fine serrations; synapticulae absent or present.
Gardineroseris Great variation in growth form and colony size. Round, oval or elongate polygonal; 2-3mm in diameter. Walls lacking or present; collines may enclose several calices. Septa in cycles, about 50 in a calice 3mm in diameter; margin smooth or granular; inner ends of septa broad.
Leptoseris Often leafy, my be encrusting. Colonies small to medium size. Outline indistinct; approx. 2-10mm in diameter. Collines may be present, enclosing a series of mouths. Numerous and run uninterrupted b/w centers; margins with fine or coarse serrations; synapticulae absent of a few present.
Pachyseris Foliaceous to massive, often large. Calices in series; 2-5mm across valleys. Distinct collines with calices in the valleys. Numerous and parallel, about 40-50/cm; margins finely serrated; synapticulae absent.
Coeloseris Massive, rounded colonies of medium to large size. Rounded polygonal; 2-5mm in diameter. Distinct shared walls. Well spaced and in cycles; some join to narrow ridge along the midline; 20-30 in calice 3mm in diameter; margins smooth or with a few spines; synapticulae absent.
