Catalog entries: Chrysochromulina cyathophora
Original description: Cell subspherical, c. 3.0 µm (2.9-3.3 µm) in diameter when dry; two flagella 10-12 µm long and a haptonema c. 7 µm long when extended. Scales of two kinds. Inner scales plate-like, circular, approximately 0.8 µm in diameter, with a pattern of concentric ridges on the distal surface (c. 10 per 0.1 µm). Outer scales cylindrical, almost straight-sided, diameter c. 0.2 µm , 0.5-1.1 µm long, and proximally attached to a base-plate. The proximal baseplate surface is indistinctly radially striated at the periphery. The thickness of the cylinder wall decreases abruptly about two thirds from the base.
