Original description: Microsphère à pores larges, irrégulièrement polygonaux. De huit à dix trabécules radiaires donnant naissance au tissu spongieux. Ce dernier, non limité extérieurement par une plaque grillagée, et assez grossier, rappelle d'assez près celui de Plegmosphaera entodictyon. C1 : 25µm. C2 : 320µm.
[Microsphere with large pores, irregularly polygonal in shape. 8 to 10 radial trabeculae building the spongious tissue. This tissue is not closed on the external side by a lattice plate; it is rather coarse and close to the spongious tissue of Plegmosphaera entodictyon. C1: 25µm. C2: 320µm. (In French. Translated by J.P.C.)]
