Morphology

Size
15-17 µm long, 3.5-4.0 µm wide (UK population), 10-25 µm long, 3.5-4.5 µm wide (Krammer 1997).

Symmetry
Isopolar, symmetrical or very slightly dorsiventral.

Striae
Parallel or slightly radiate, 25-27 in 10 µm (UK population), 24-25 in 10 µm (Krammer 1997).

Axial area
Narrow, linear.

Central area
Small, indistinct.

Raphe
Filiform, positioned in the centre of the valve.


SEM morphology
Proximal raphe fissures slightly dorsally curved, distal raphe fissures slightly ventrally deflected.
