Description Small to medium-sized cells (32–42 μm in length). In side view, somewhat irregularly egg-shaped, rather asymmetrical with an apex narrower than the broad rounded antapex; ventral contour until R3 slightly convex, and from there onwards, more or less broad and rounded; dorsal contour always more strongly convex than the ventral one. The broader depth of the cell is at the height of R3, or slightly lower. The ratio between the maximum length and dorso-ventral depth (L/D) of the large hypothecal plates (LHP) ranges from 1.3 to 1.4. These LHP exhibit a rough areolation, and most of the areolae have a central pore. [details]

[details]Harmful effect OA found in picked cells from Galicia (7 pg/cell of OA, Raho et al. 2008) and in cultures from Gulf of Texas strains (Fux et al. 2011). Blooms have been associated with DSP outbreaks in Termaikos Bay (Papaefthimiou et al. 2010) and the exceptional 2008 bloom in Texas (Deeds et al. 2010; Swanson et al.2010; Campbell et al. 2010).
Dinophysis ovum is often misidentified as D. acuminata. However, strains from Galicia, Greece and Texas were well separated from D. acuminata based on the sequence of the mitochondrial cox 1 gene (Raho et al. 2008). [details]
