Nodosarioidea are characterized by planispirally coiled, uncoiled, or straight chambers, or which are coiled about a longitudinal axis. Test (or shell) walls are of finely perforate, radial laminated calcite. Apertures are peripheral or terminal, variable in form. Septa, dividing the chambers, are unilamellar, composed of a single layer, while the outer walls may be multilamellar, composed of multiple layers built up with the addition of new chambers.
