Original Description

Diagnosis: A species of Larcospira characterized by its thick-walled, uniformly perforate cortical lattice shell and irregularly swollen or invaginated margin.

Description: The skeleton consists of three lattice whorls that appear as simple lattice shells in plane view. The whorls are interjoined by a multitude of delicate radial beams that do not penetrate the cortical shell as spines. Cortical shell thick walled, densely and uniformly perforated by small, round pores. Medullary shells ovate in outline. Cortical shell margin varies from smoothly ovate to laterally constricted with alternating swellings and invaginations.

Etymology:
The trivial name is derived from the Latin word bulbosus, meaning swelling.
