Eliášová, 1991


Radial elements are anastomosing septa (?) with irregular and sparse pores. The internal edge shows lobes protruding in the axial cavity which build a parietal columella. Lateral faces displays pointed granules whose organisation is badly known. Septal radial symmetry disturbed by increase and difficult to decipher in term of hexameral symmetry. Bilateral symmetry observed through torsion of septa. Zigzag septothecal or parathecal wall. Endotheca made of vesicular dissepiments. Synapticules present. Microstructure made of neorhipidacanth trabecules ?
