picture info	Stonewort Charales is an order of freshwater green algae in the division Charophyta, class Charophyceae, commonly known as stoneworts. Depending on the treatment of the genus ''Nitellopsis'', living (extant) species are placed into either one family (Characeae) or two (Characeae and Feistiellaceae). Further families are used for fossil members of the order. Linnaeus established the genus '' Chara'' in 1753. Taxonomy The higher level classification of green algae was unsettled . AlgaeBase places Charales within the class Charophyceae and its circumscription of the division Charophyta. Families The number of families and their division into genera varies. , AlgaeBase accepts two families containing some extant species and four families containing only fossil species: Characeae S.F.Gray Feistiellaceae Schudack † Aclistocharaceae X.G.Zhou (may be included in Characeae) † Atopocharaceae R.E.Peck (may be included in Clavatoraceae) † Clavatoraceae Pia † Porocharaceae Grambast Al ...

picture info	Characeae Characeae is a family of freshwater green algae in the order Charales, commonly known as stoneworts. They are also known as brittleworts or skunkweed, from the fragility of their lime-encrusted stems, and from the foul odor these produce when stepped on. In some treatments, the Characeae includes all the living (extant) species of Charales; this circumscription is followed here. In other treatments, the genus ''Nitellopsis'', which has both extant and extinct species, is placed in a separate family, Feistiellaceae. Description Living members of the Characeae ''sensu lato'' grow in freshwater and brackish environments worldwide, and have large, macroscopic thalli growing up to 120 cm long, they are branched, multicellular, and use chlorophyll to photosynthesize. Their only diploid stage in the life cycle is the unicellular oospore. They may be called ''stoneworts'', because the plants can become encrusted in lime ( calcium carbonate) after some time.
