Braarudosphaera bigelowii ALT

Original description: Cells motile, elongate, ovate, 10-26 µm long, 5-10 µm wide, dorsoventrally compressed. Two flagella and one haptonema arising close together at one end; fiagella equal, smooth, homodynamic, 8-20 µm long; haptonema shorter than fiagella 2.5-4.5 µm long. Plastids two, golden-brown, lateroparietal.
Scaly investiture present, visible with light microscope. Scales of four forms;

• largest elliptic plates 2.2-5.0 µm long, 1.3-3.5 µm wide, distal surface with a peripheral raised flap with short basal vertical bars and a central irregular fibrillar pattern, proximal surface with a pattern of radiating and crescentic ridges; 
• medium-sized elliptic plates 1.3-4.1 µm long, 0.7-2.8 µm wide, superficial patterns similar to above, in addition a peripheral band of coarse fibrils and a marginal pattern of pores and ridges on the distal surface; 
• smallest plate scales narrowly elliptic, usually associated with bases of spines, 1.3-2.8 µm long, 0.6-1.2 µm wide, distal surface with irregular fibrils and a broad cross-striated peripheral border, proximal surface with radiating ridges; 
• spines 20-31 µm long, usually posterior sometimes also anterior, shaft cross-banded, finely attenuated distally broadening to a spoon-shaped base, one surface of base with irregular fibrils the other with radial and crescentic ridges. Marine.
