Distributional notes
Nitella flexilis is a cosmopolitan species, and it is also widespread in Europe. In the Nordic countries it is found in Sweden (Hasslow 1931, specimens from UPS and S), Known distribution of Nitella flexilis in the area. Finds after 1970. Rings are old finds and finds in Denmark (Olsen 1944). Finds (after 1960) in Shetland, Orkney and Scotland are after Moore (1986). Stars on the Greenland map is N. opaca vel flexilis. References are given in the text. Denmark (Olsen 1944); Finland (Langangen et al. 2002), Norway (Langangen 1974, 2007), Faroe Islands (Langangen 1996), Iceland (Langangen1972) and Greenland (Langangen et al. 1996). In Norway the species is found scattered through the country. The species is also found in Shetland, Orkney and Scotland (Moore 1986). In Finland this species is scattered throughout most of the country. In Sweden, where the finds are after Hasslow (1931) there are very few finds in northern parts, which most probably is due to lack of collections. The finds in North Sweden are based on specimens in the herbaria of Stockholm (S) and Uppsala (UPS). In Norway there is a similar situation. Nitella flexilis is found over large geographical areas in the Nordic area, and together with the finds in Faroe Islands, Iceland and Greenland it makes up the northern border for the European distribution range. - (10 Jan 2012) -

Habitat notes
Prefers permanent, neutral to acid waters, on siliceous substrate, often associated with Ranunculus or Myriophyllum; occurs in rivers with shallow, slowly moving water, lakes and peaty marshes, and forms perennial populations in deep lakes (Muller et al., 2017). - (31 Oct 2017) - Wendy Guiry

Conservational notes
Redlisting and status: Norway NT (Kålås et al. 2006). The species has been found in many recent localities both in Finland and Norway. In Sweden the number of recent sites (1975- 1999) are c. 130 according to Blindow (2000). In Faroe Islands and in Iceland the finds are old. In Greenland there is one find from 1977. Proposed red list status for the whole area is LC (least concern). - (10 Jan 2012) -

General environment
This is a freshwater species.

Common names

(as Nitella flexilis (Linnaeus) C.Agardh)
Swedish: Glansslinke (Tolstoy & Österlund 2003).

Description
Nitella flexilis differ from Nitella opaca by being monoecious. It is not possible to separate the two species in sterile condition.

Habitat
Nitella flexilis is found in many types of habitats; Lobelia lakes, Potamogeton-lakes, high mountain lakes, small ponds, ditches, rivers and also slightly brackish water, but it seems to prefer soft oligotrophic waters. N. flexilis is also found in cold areas. Kashimura (1969) found that the species developed best at low temperatures, with the best growth of the gametangia at 5-10oC. The species has fertile plants from May to September and ripe, black oospores from July onwards. N. flexilis var. fryeri is markedly protandrous. It has been found in Norway. In some lakes, probably with unfavourable conditions (temperature) one can find only sterile specimens which must be named Nitella opaca vel flexilis.
