Original Description

Rundlich linsenförmige Schwammscheibe, die in ihrer Mitte einen kleinen Discus trägt, in dem die Schwammzellen dichter stehen, und von dem radiale feine Stäbe auslaufen. An der Peripherie ist die Schwammschale durch einen umlaufenden Balken geschlossen, und nur an einer Stelle ist dieses nicht der Fall, und bilden dort die Kieselbalken des Schwammgerüstes kleine Zäckchen, so dass es wie eine Mündungsöffnung aussieht. Am Rande treten 16 kleine Zacken in regelmässigen Abstand vor, die Fortsetzungen der radialen Balken.
[Roundish lenticular spongious shell, with an inner central small disc made of more dense spongious cells from which radiate thin beams. Periphery of the spongious shell ending in a circular border, continuous excepted at one point where siliceous bars of the spongious network protrude outside as small indentations looking like an aperture. On the border 16 small thorns distributed at regular intervals. (In German. Translation by J.P.C.)]

Diameter of the disc: 0.2 mm, diameter of the inner disc: 0.033, average size of the polygonal to circular pores: 0.003 - 0.005. Length of the small thorns of the border: 0.003 - 0.013.]
Very rare.

Etymology:
No information given, but: Latin craticulata, -a -um = baking grid-like
