Original Description

Shell spherical, with circular or roundish pores of very different size. The smaller pores very numerous, without coronal of spines, roundish, about as broad as the bridges. Twenty to thirty pores in the half meridian of the shell. Between them, irregularly scattered, a small number (eight to twelve) of very large circular pores, one-third to one-half as broad as the radius of the shell, armed with a coronal of six to nine parallel, straight, acute spines, about half as long as the radius of the shell.

Size:
Diameter of the shell 0.1 to 0.13, of the smaller pores 0.002 to 0.004, of the larger armed pores 0.02 to 0.03; length of the spines 0.03 to 0.04.

Editors' Notes
Haeckel listed Choenicosphaera nassiterna under the subgeneric name Choenicosphaerium, but did not include the subgeneric name in the species name.
Synonymized with Acrosphaera spinosa (Haeckel) by Popofsky, 1917[comment from RadWorld database]
