Cosmarium is a genus of fresh water organisms belonging to the Charophyta, a division of green algae from which the land plants (Embryophyta) emerged Cosmarium is a common free floating freshwater placoderm desmid found in ponds, lakes, ditches, and other reservoirs, though some species (e.g. C. salium) are found in brackish water . This specimen was collected from the ponds near physical block and also from the stagnant water which is located just below the MPH Hostel. Description Cosmarium cyclicum; Cosmarium dentiferum; Cosmarium depressum; Cosmarium dilatatum; Cosmarium formosulum; Cosmarium granatum; Cosmarium impressulum; Cosmarium laeve; Cosmarium margaritiferum; Cosmarium meneghinii; Cosmarium ornatum; Cosmarium orthostichum; Cosmarium phaseolus; Cosmarium protractum; Cosmarium punctulatum; Cosmarium pygmaeum; Cosmarium pyramidatu Cosmarium is a very specious artificial genus, most probably of polyphyletic origin. 3‒5 Due to the disproportionate number of species included in the genus and its very much suspected artificiality, there are very few taxonomic revisions and floristic works published covering a broad area.

Cosmarium botrytis C. botrytis is a frequently recorded, medium sized, granulate Cosmarium species that may be readily confused with similarly shaped species. Semicells are about pyramidal in outline Cosmarium bromelicola sp. nov. is a new desmid species described from samplings carried out in bromeliad tanks (phytotelmata) from an area of rocky outcrops at Serra da Jiboia, Bahia State.

It lacks the isthmus of the general description above but has at the extreme ends of each semi-cell a small spherical vacuole in which varying numbers of tiny particles can be seen in constant agitated motion
Genus Cosmarium: Description: Cells single. Most taxa slightly compressed, therefore elliptical in vertical view. Median incision is usually pronounced but unlike in Euastrum or Micrasterias cells are not lobed. Wall ornamentation varies greatly, ranging from smooth to punctate, scrobiculate or granulate. Large genus, probably in need of splitting Desmid of the month November 2005 Cosmarium pericymatium. Cosmarium pericymatium belongs to a small group of desmid species that can stand long periods of severe drought (Brook 2001). With its thick-set cell shape (low cell surface to content ratio) and thick cell wall evaporation rate is reduced Cosmarium sp. (desmid) near a Sphagnum sp. leaf.

However, no studies have yet examined phytoplankton in lagoons that changed to freshwater, such as Cheonjin Lake. The present study examined the algae from Cheonjin Lake. Samples were collected at monthly inetrvals from May 2017 to April 2018, from the surface layer using a plankton net (mesh size 20 μm), and.
