Original Description
Druppulida with simple ellipsoidal cortical shell and double medullary shell; without spines or polar tubes.

Etymology: From the Greek prunulum = little-plum"

Extra details from original publication
The genus Prunulum differs from Druppula in the double (not simple) medullary shell, which is sometimes spherical, sometimes ellipsoidal; it may be derived either from Druppula by duplication of the medullary shell, or from Thecosphaera by prolongation of one axis.
