Description
Cells having at least two forms. Cells nonmotile,
spherical to subspherical, measuring 8—
12 µm, having a posterior vacuole and hyaline
hollow space. Two yellowish chloroplasts, each
with an immersed pyrenoid. Nucleus central, Golgi
body parabasal. Two short flagella, 1.5 µm at
longest. A non-coiling haptonema, 12—18 µm
long. Periplast covered with two different types
of scales. The outer layer consisting of hat-shaped
siliceous scales, oval to irregularly ellipsoidal in
top view, measuring 5—7 and 4—6µm across the
axes, having many small pores (0.1—0.3 µm) in
bulging central area. The brim of scales recurved,
not perforated. The inner layer of organic scales,
elliptical, measuring 0.6 and 0.4 µm across the
axes, with 92—100 rough radial ridges and fine
concentric patterns.
Motile phase cell subspherical to pear-shaped.
Chloroplasts two, yellowish. Two equal flagella,
15—25 µm long. A non-coiling haptonema, 12—
18 µm long. Periplast covered with short spine
scales, oval to ellipsoidal in top view, with a
maximum area of 2 and 3 µm across the axes,
many small pores arranged in a radial pattern
(72—120), ridge, marginal thickening.
