Diagnosis

Reference	Diagnosis
F. Debrenne et al. 2015	Skeleton nonspiculate, calcareous cup of microgranular microstructure and (with few exceptions) original magnesium calcite composition. Cup generally of archaeocya- than architecture with one or two porous walls bounding inner or central cavity respectively; porous to aporose septa, pseudosepta, taeniae, pseudotaeniae, pseudotaenial network, dicty- onal network, syringes, and/or tabulae may form in intervallum; a minority are of chae- tetid (intervallum with calicles) or thalamid architecture (cup consisting of successive chambers). Solitary or modular. Secondary calcareous skeleton may be present.
