Farinacci & Howe catalog pages: V. cereus *

Morphology: Coccosphere shape unknown, collapsed specimens spherical–subspherical in outline, 5.7–7.2 lm in diameter (excluding processes). Coccosphere dimorphic, monothecate, bearing 50–60 ordinary (body) coccoliths and 19–21 tubular coccoliths. Body coccoliths elliptical, 0.6–1.0 µm x 0.8–1.5 µm, and 0.3–0.6 µm in height, flaring outer wall elements, and inner cycle of much shorter wall elements. Central area apparently open.
Tubular coccoliths identical to body coccoliths, but with central bar across short axis, supporting distally tapering quadrangular process, 1.5–2.6 µm long. Process wall comprising single row of brick-like elements, distally diminishing in size (from 0.2–0.4 µm to 0.1 µm in width), with tip composed of two back-to-back elongate elements (about 0.5 µm long). [from Andruleit & Jordan 2017, slightly edited]

Ecology & Biogeography: Lower photic zone, rare.
