In recent Fungid corals colony formation is by intra-tentacular budding, extra-tentacular budding never occurring. Intra-tentacular budding in Pavona is on the distomodaeal, triangular tristomodaeal and triple stomodaeal modes, with direct linkage, in Echinophyllia and Leptoseris is usually accompanied by mesenterial curvature and cleavage, in Psammocora is peripheral. Intra-tentacular budding results in the cyclic polystomodaeal condition; the subsidiary polyp areas are originally arranged in concentric rows around the primary polyp area which, during growth, shifts from a central to an excentric position. Cyclic polystomodaeal condition is primarily continuous, discontinuity being secondary. Discontinuity of the cyclic polystomodaeal condition, when it occurs, is at first due to the appearance of concentric ridges, subsequently of radial ridges. When the two systems of ridges are equally well developed, their intersection results in short polystomodaeal, tri-, di-, or monostomodaeal polyps.
