Common names

(as Chara tomentosa Linnaeus)
Danish: Tyk kransnål (Langangen 2007).

English: Coral Stonewort (Stewart & Church 1992).

Finland: Rödsträfse (Langangen 2007).

Norwegian: Rødkrans (Langangen 2007).

Swedish: Rödsträfse (Tolstoy & Österlund 2003).

Description
In this species the plants are robust, from 10  60 cm long, and the axis is up to 2 mm in diameter. Parts of the plants, especially young plants have a red colour which is an important character for the determination of the species. Plants from deeper water are green. The plants are usually heavily encrusted. The branchlets are 6- 8, short, each with 4- 5 segments. The stem cortex is diplostichous, tylacanthous. The spine cells are solitary or geminate, swollen, and similar to the stipulodes and the bract-cells. The species is dioecious. Gametangia are at the 2-3 lowest branchlet nodes. The oogonia are up to 1.2 mm long. The oospore is brown. The antheridia are very large and up to 1.5 mm in diameter.

Habitat
Chara tomentosa is found both in freshwater and brackish water, the last in the Baltic Sea (red parts on the map). It is found within the salinity area 4.5  7.5 PSU, and it is presumed that lower or higher salinity are natural limits for the distribution of the brackish water form. The species is found in sheltered places, bays, coastal lagoons on soft muddy bottoms down to 3 m depth. In freshwater Chara tomentosa is only found in calcareous waters, Chara- to Potamogeton-lakes. C. tomentosa is a perennial species. It grows down to a depth of 4-5 m, on limerich sediments. Often the species is found in dense, mixed populations with other Chara-lakes species. Fertile plants are normally found in June to September. Ripe, brown oospores are rare, and sexual reproduction is therefore ineffective. This is, in addition to its special habitats one of the factors which limits the distribution of the species.
