Koliella is a genus of green algae in the order Prasiolales. Members of this genus are found in freshwater plankton, but some are also found on snow and ice.

Ancylonema is a genus of green algae belonging to the family Mesotaeniaceae. This genus is known to include psychrophilic species found on surfaces of glaciers and ice sheets. Recently, a mesophilic species, Ancylonema palustre, has also been discovered from the temperate moorlands of western Germany. One example of the genus is the species Ancylonema nordenkioeldii, which has been known to be an important part of the algal communities on glacial ice surfaces in Greenland and Norway. Psychrophilic members of Ancylonema have been recorded to participate in algal blooms on glacial ice surfaces,
