Original Description
Radial spines eight, three-sided prismatic, with three spirally contorted edges, eight to ten times as long as the diameter of the inner shell-cavity (the free distal portion twice to three times as long). From each spine arise at equal distances thirty to thirty-five verticils of branches, which decrease in size towards the distal end. Each verticil is composed of six forked branches (two from each spine-edge); the inferior are richly ramified, and form by their connection the loose spongy framework; the distal branches bear on the free end elegant spathillae (as in the following species). Surface covered with innumerable straight bristles, as long as the cavity radius, and ending with a spathilla. Diameter of the central capsule about equal to the radius of the spongy sphere, its membrane double-edged.

Size: Diameter of the spongy shell 1.4 mm, of its inner cavity 0.14, of the central cube 0.02, of the central capsule 0.5 to 0.6; lenght of the spines 0.9 to 1.2, breadth 0.02.

Editors' Notes
There was no illustration of this species in Haeckel (1887)
Haeckel listed Octodendron acaucaria under the subgeneric name Octodendridium, but did not include the subgeneric name in the species name.
