Original Description
Cortical shell very thin walled, with irregular, polygonal meshes (sixteen to eighteen on the radius), three to six times as broad as the bars. Both medullary shells with smaller pores of the same structure. Radial proportion of the three spheres = 1: 2.5: 7; radial connecting beams between them very thin and numerous (one hundred and twenty to one hundred and fifty or more), each prolonged outside into a short three-sided pyramidal spine, as long as the radius of the inner shell. (Similar to Haliomma capillaceum.)

Diameter of the outer shell 270µm, middle 100µm, inner 40µm; cortical pores 10 to 20µm, bars 3µm; length of the spines 20µm, basal breadth 5µm.

Editors' Notes
Haeckel listed Actinomma capillaceum under the subgeneric name Actinommura, but did not include the subgeneric name in the species name.
