Tropiphyllidae

Beauvais, 1981

Diagnosis

Radial elements are compact septa, generally free, accidentally anastomosed, wavy rather than straight. The inner edge of septa is attenuate. The lateral faces are covered by continuous menianae whose outer rims are directed distally and ornamented with few coarse granules. The menianae alternate in level with neighbouring septa. Trabeculae of 160-350 _m in diameter have axes that bifurcate at the level of menianae. Short lateral axes grow in the interseptal space and subdivide again. Symmetry of septal apparatus not well known. Synapticulae absent ?, vesicular dissepiments present.
