Description
Colonies grown on agar mounded, grainy, moist; yellow to olive when young, becoming bright orange to red with age. Cells solitary, variable in form. Cells crescent to lemon-shaped with pointed ends when young, becoming oval to almost spherical with age. Small protrusions evident at poles in some cells. In liquid cultures, long thin extensions evident at each end of crescent cells. Crescent cells 3-8 microns wide, 1.5 -2 times long as wide. Oval cells 7-21 microns wide by 8-24 microns long. Uninucleate. Chloroplast parietal with a single lobe. Clear pyrenoid with obvious starch hull. Granular cytoplasm. Orange to red oil droplets, sometimes copious, in aging cells. Two to eight autospores produced by longitudinal division. No motile stages or colony formation observed in liquid culture.
