Septa numerous, long, somewhat thickened; some major septa reaching axis. Tabularium narrow (14-1/s mature corallite diameter); dissepimentarium wide, with nonuniform large and small dissepiments, most of which are elongate. Peripheral dissepiments nearly flat, commonly very elongate, and in part lonsdaleioid. Calice shallow with broad, commonly reflected rim and central pit. |
