Amphora ovalis (Kützing)

Scale bar 10 µm Assymetric biraphid diatom. Valve shape semi elliptic, dorsal margin arched.  Raphe deflects dorsally in the central area and ventrally towards apices. fascia on the ventral side, absent on a dorsal side. Dorsal striae interrupted. Collected sample was a foam from between the rocks.
