Prorocentrum consutum Chomérat et Nézan 2010
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.
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.
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.
