Original description: Polycystinum compositum e Calodictyis. Testula silicea plana spangioso-cellulosa, lobato-stellata. Cellulae disci Spongiosi non aut obscure concentricae. Membrana cellulosa radios totos coniungens.

Ab Histiastro fossili defectu cellularum disci spangiacci concentricarum differt.


Translated description: Composite polycystin of the Calodictya. Test small, siliceous, flat, spongy-porous, lobate-stellate. The pores of the spongy disc are not, or only obscurely, concentric. A porous membrane connects all the radii.

Differs from the fossil Histiastrum lacking concentric pores on the spongy disc. (Translated from Latin by E.M.R. and W.R.R.)]
Remarks on original description: [Campbell [401:D94] designated D. profunda Ehrenberg, 1872a as the type species of Dictyocoryne. However, this seems inappropriate as this species was not among those first subsequently assigned to Dictyocoryne. Species first subsequently assigned to Dictyocoryne are: D. euchitonia in Haeckel, 1862 and Spongaster tetras in Ehrenberg, 1860b.

Dictyocoryne Ehrenberg, 1860a, [775:767] is a Nomen Nudum.]
