Classification:

Kybotion  Pascher  1940;  1 of 3 species descriptions is currently accepted taxonomically (Guiry and Guiry 2014).

Order Hibberdiales;  Family Stylococcaceae.

Morphology:

Loricate sessile unicells with one or two chloroplasts, and with a cytoplasmic pseudopod (rhizopodium) often extending through the narrow opening at the apex of the lorica, presumably for capturing bacteria.  Lorica has the shape of a flask ~10 microns diameter at the base, lying on its side against a substrate. 

Asexual reproduction includes a flagellated zoospore that exits the lorica, moves to a new location, and becomes amoeboid during the “settling” to become sessile and construct a new lorica).

Similar genera:

Lagynion has an upright sessile lorica.

Habitat:

Epiphytic in generally oligotrophic and slightly acidic freshwater lakes.
