Catalog entries: Collosphaera spinosa

Original description: Die kieselige Gitterschale der in dem gallertigen Meerqualster zerstreuten Nester mehr oder weniger kugelig, mit unregelmäfsigen und ungleichen rundlichen Löchern und zahlreichen zwischen denselben schief abstehenden, kurzen Stacheln, höchstens 1/5 so lang als der Durchmesser. Centralkapseln (Nester) kugelig, farblos.
[Siliceous lattice shell, included in the gelatinous protoplasm distributed around the central capsule, more or less spherical, with irregular and irregularly rounded pores, and numerous short spines obliquely oriented, at most 1/5 as long as the diameter of the circular, translucent, central capsule. (In German. Translated by J.P.C.)]


Published descriptions

Nigrini 1967 - Collosphaera spinosa

Shell thin-walled, smooth, spherical, with numerous, irregularly scattered, subcircular pores of variable size, 1-4 times as broad as the bars. Short spines, usually mounted on conical elevations, project randomly over the shell surface, either singly from pore margins or from between the pores. Spines are usually conical, but may be quite sharp; often they are fenestrate near the shell and sometimes arise from as cluster of small pores rather than from a single pore. Probably these pore clusters form when a single pore is divided by a growing spine.
