Taxonomy:
Catalog entries: Chrysochromulina pyramidosa
Original description: Cell saddle-shaped, 3 µm long x 4 µm wide; two flagella 10-13 µm long, and a haptonema 5-6 µm long. Scales of two types. Some are platelike , circular, approximately 0.7 µm in diameter, with a pattern of radiating ridges (24 in number), and 7-8 nearly equidistant concentric rings, the ring at the edge being thicker than the others. The second type of scales have a plate-like base which is constructed in a similar way with a diameter 0.8-0.9 µm, 27-28 radiating ridges, and 8-9 concentric rings. The innermost rings are equidistant, the distance between the outermost thicker ring and the next ring somewhat greater. From the margin of the plate four thick struts branch off creating a pyramidal superstructure.
