Cormus formed of large, irregular and loosely anastomosed tubes with many oscula. Water-collecting tubes are absent. Living specimens have a yellow cormus, which becomes white after preservation in ethanol. The skeleton has no special organisation and it is composed of only equiangular and equiradiate triactines. Actines are cylindrical and slightly undulated near the tip, which is rounded.
