Original description: [Cookson and Eisenack, 1958, p.46]:

Shell sphaerical, smooth with a number of processes of unequal length and width, which, by their branching and coalescence, give rise to a loose external network. Some of the main branches are flattened and relatively broad; short branches bearing 3 or 4 slender hairs are developed at or near some of the points of branching.

Dimensions:
Holotype - overall diameter c. 185 µm, diameter of shell c. 104 µm.
