Original Description
[... An external spongious, siliceous, meshwork of extremely thin, filament-shaped, bars anastomosed into a bush, with radial rays irregularly distributed as in a spider-web, is developed at an important height above a corpus, so that the mean distance between the meshwork and this corpus do not exceed the diameter of the last one. The meshes of the filamentous meswhork are very wide, up to 1/4 or 1/5 of the diameter of the lower corpus. The meshwork extends so much towards the exterior that it is there mostly subdivided into filamentous extensions that are related by many thin branches to four-sided radial spines not entirely symmetrically distributed. Externally, these spines extend shortly above the spongious tissue and some of them (up to a quarter disappears) continue inside in loosing their sides but with isolated nodes, down to the small perforate nuclear shell, inside which some crossed bars constitute a second smaller nucleus. The diameter of the inner nucleus is a third from the diameter of the first nucleus. The meshes of the nuclei are circular, they are up to two times as wide as their frames on the first nucleus, but pores and frames, however a third smaller, are of same size on the inner nucleus. The radial spines have elevated sides producing a foliate cross section. Yellow vacuoles located, as usual, between the bases of the radial pseudopodes, above the smooth capsule from which they extend. Some red pigment is located in the median part of the corpus.
