This is a freshwater species.
The plants are from 5 to 80 cm long and always encrusted. The axis is 0.5 1.5 cm in diameter. The internodes are long and each node has whorls with 8-12 branchlets, each with 7-9 segments. The stem cortex is diplostichous, tylacanthous. The spine cells are more or less developed, and varying from papillous to the length of the stem diameter, solitary or in clusters of 2-3, and they are often scattered. The plant is monoecious. The gametangia are conjoined at the 3-4 lowest branchlet nodes. The oogonium is solitary, up to 1.3 mm long. The oospore is brown to dark brown. The antheridium is up to 500 m in diameter.
Chara aculeolata a freshwater species which can tolerate slightly brackish water. It is found in Chara- and Potamogeton lakes and is bound to lime-rich localities. It grows on marl gyttje.
