Secondary Description
Author: Wehr, J. D. and Sheath, R. G., (eds.), 2003
Secondary Description:
The loricae of members of this genus are composed of pectic material including compounds of iron and/or calcium. There are both a long and a short flagellum, but the short flagellum is usually not detectable with light microscopy. The long flagellum emerges through a pore in the lorica. Lorica shape, size, and presence or absence of stigma and pyrenoids are the main features distinguishing species, all of which are planktonic.
