Original description: E Polycystinorum classe. Discus suborbicularis cellulosus spongiaceus, siliceus, margine regulari destitutus. Rabitus fragmenti, sed frequens forma. Nonnullae ad Rhopalastri lagenosi apices radiorum fractos specie prope accedentes formae, frequentia et constants typo memorabiles et discernendae.

Translated description: Of the class Polycystina. Disc subcircular, porous, spongy, siliceous, without a regular margin. It has the appearance of a fragment, but is a frequent form. It is necessary to bear in mind that members of this genus can closely resemble (and must be distinguished from) the brokenoff apices of the radii of Rhopalastrum lagenosum, which can occur frequently and have a constant form. (Translated from Latin by E.M.R. and W.R.R.)]
Remarks on original description: [Premature name in Ehrenberg, 1854a [762:70]; ""Neue Genera sind nur 3 unter allen 150 Formen, zwei in einer einzelnen Art. Spongodiscus und Cenosphaera unter den Polycystinen""; Nomen Nudum
