Suborder Dendrophylliina Vaughan & Wells, 1943

Diagnosis. Solitary and colonial. Wall synapticulothecal, irregularly porous. Septa structurally similar to the caryophylliids but usually secondarily thickened, more or less porous, with margins wholly smooth or partly dentate. Septa usually following the Pourtalès plan. istic of the Caryophylliina , but the porosity and thickening of the septa, due to irregular trabecular growth, and the perforate synapticulothecal wall are conditions of specialization unknown in that group; the latter features are more characteristic of the fungiid group. It is suggested that the group originated from a caryophylliid-like ancestor in which very irregular trabecular growth leads to septal thickening and perforation and replacement of septotheca by synapticulotheca, and these in turn broke up extratentacular mesenterial extensions into canaliculate prolongations of the coelenteron through and over the wall. Septa usually following the Pourtalès plan.
