Description:
Cells are sausage shaped and larger than J (Scendesmus). They often appear in pairs overlapping with each other perpendicularly.
Notes:
Green Lakes: Morphotype B. In Green Lakes, was formerly was called morphotype BY and identified to species level under a different genus: Rhabdogloea scenedesmoides.

Secondary Description
Author: Wehr, J. D. and Sheath, R. G., (eds.), 2003
Secondary Description:
Cylindrical cells are arranged more or less in the same direction, but usually not chainlike, irregularly distant, in microscopic, irregularly oval or elongated mucilaginous colonies. The mucilage is fine, homogeneous, colorless, diffuse or delimited at the margin, and sometimes indistinct. Cells always are cylindrical, rod-shaped, or slightly curved, rounded at the ends, sometimes several times longer than wide, (2)4-12(33) x (0.5)1-3.5μm, with pale blue-green, greyish, or olive-green cell content and no obvious gas vesciles. This species never occurs in masses, but several species commonly occur in plankton of large oligotrophic and mesotrophic lakes.
