Original Description

Shell thick walled, thirteen times as broad as one mesh. Pores regular, circular, three times as broad as the bars, with an elegant six-lobed frame (Pl. 28, fig. 1b). In the intervals between the six lobes of each mesh arise six conical radial spines (half as long as the radius), six around each pore. (Differs from the similar Haliomma flosculentum [for flosulentum read lirianthus - G.D.], Pl. 28, fig. 1, in the absence of an enclosed medullary shell and the stronger development of the spines.)

Diameter of the shell 130µm, pores 10µm, bars 3µm; length of the spines 30µm.

Editors' Notes
There was no illustration of this species in Haeckel (1887)
Haeckel listed Acanthosphaera flosculenta under the subgeneric name Rhaphidococcus, but did not include the subgeneric name in the species name.

Haeckel here compares A. flosculenta to Haliomma flosculentum, pl.28, fig.1. This latter species name, however, is not known. Haeckel probably intends Haliomma lirianthus, the name of the species illustrated on pl.28, fig.1.
