Pseudo-nitzschia H.Perag. in H.Perag. & Perag.
Pseudo-nitzschia cf. cuspidata (Hasle) Hasle emend. Lundholm, Moestrup & Hasle, 2003
Pseudo-nitzschia cf. cuspidata. TEM micrographs. (A and B), Scale bars = 10 µm. (C) Scale bar = 5 µm. (D) Scale bar = 1 µm. (E) Scale bar = 0.5 µm. (A and B) Whole valves with pointed ends. (C) The two ends of one valve. (D) Middle part of valve showing distal (upper) and proximal (bottom) mantles, uniseriate striae, central interspace and central nodule. (E) Part of the valve with perforate poroids; note variation in poroid structure, usually hymen of poroids divided into two perforated parts.
