Description
Laminae extensive, thick, typically ordinicellular but commonly showing a central clear zone or opaque axis, pierced by large pores joining the galleries above and below. Pillars short, expanded above and below at laminae, systematically superposed across successive laminae, forming grid with laminae, microstructure vacuolate, cellular, compact.
