Chlorolobion, sometimes spelled Chlorolobium, is a genus of algae belonging to the family Selenastraceae.[2] The species of this genus are found in freshwater habitats in Europe and America.[2]

Chlorolobion consists of single cells. They are either free-floating, or in the case of Chlorolobion obtusum, attached to the carapaces of freshwater crustaceans. Cells are asymmetrically fusiform (spindle-shaped) with one side being more curved than the other. The tips of the cells are rounded. The single chloroplast is plate-like and wraps around the inside of the cell, and contains one (rarely two) pyrenoids.[3] Unlike other genera in its family, Chlorolobion has pyrenoids that are surrounded by a starch sheath, making them visible in the light microscope.[4]
