) s’étendent en larges croûtes minces et souples de couleur beige-saumon de 1,5 mm d’épaisseur. La couleur, due seulement aux zoïdes, disparaît en formol. La surface est lisse. Les siphons buccaux s’ouvrent dans un cercle ayant peu de spicules, d’où un aspect ponctué de la surface des colonies. Les ouvertures cloacales communes sont larges, bordées d’une courte cheminée de tunique sans spicules. Les spicules sont denses, surtout dans la couche basale des colonies. Les zoïdes sont suspendus dans des piliers de tunique qui traversent une vaste cavité cloacale commune. Les larves sont contenues dans la couche basale des colonies.
