Prorocentrum consutum is a photosynthetic, marine, benthic dinoflagellate.
P. consutum contains many chlorplasts and a starch-sheathed pyrenoid that appears as a central ring under light microscopy. The nucleus is kidney-shaped and located posterior, adjacent to the pyrenoid.
Prorocentrum consutum is an oval-shaped, flattened dinoflagellate cell. Is is among the largest benthic Prorocentrum species and possesses distinct thecal ornamentation. It was first described from sands in South Brittany, France.
From Chromérat et al. 2010:
Cells of P. consutum are 57.5-60.7 μm long (mean 58.8 ± 1.0 μm, n = 10) and 52.6-55.2 μm wide (mean 54.3 μm ± 0.8 μm, n = 10) in valve view and are plainly flattened. Cell shape is roughly subcircular to broadly ovoid in valve view, and the length to width ratio varies from 1.06 to 1.12 (mean 1.08 ± 0.02, n = 10). At the anterior end, the cell is slightly narrower. The valves appear to be flat or slightly concave. The valve surface is smooth, and a ring of 90 to 107 (mean 95 ± 5.6, n = 9) large areolae (diameter 0.8-1.0 μm) runs alongside the periphery of valves.
