Catalog entries: Collosphaera tuberosa

Original description: Shell very irregular, between subspherical and polyhedral in form, but always with irregular impressions, boils or bosses, and between these different rounded prominent tubercles and ridges. Network irregular, strong, with rounded, subcircular or nearly polygonal meshes. Ten to thirty pores in the half meridian of the shell. Diameter of the meshes half to four times as broad as that of the thick bars.

Diameter of the shell very variable in the same coenobium, 0.05 to 0.2, of the pores 0.002 to 0.008, breadth of the bridges 0.004 to 0.006.
Remarks on original description: [= Collosphaera huxleyi var in Haeckel, 1862, pl.34, figs.3,9, partim.
Haeckel listed Collosphaera tuberosa under the subgeneric name Dyscollosphaera, but did not include the subgeneric name the species name.
