Common names

(as Nitella mucronata (A.Braun) F.Miquel)
Danish: Brodspidset glanstråd (Langangen 2007).

English: Pointed Stonewort (Stewart & Church 1992).

Norwegian: Broddglattkrans (Langangen 2007).

Swedish: Uddslinke (Langangen 2007).

Description
The plants are 10-30 cm high and dark green. The axis is between 0.5 -1mm in diameter. The fertile branchlets are divided two or three times, and the sterile branchlets are divided one or two times. The dactyls are 2 (rarely 3) celled, mucronate and have acute end-cells. The species is monoecious. The gametangia are conjoined. The oogonia are solitary or geminate, and often absent from the lowest branchlet nodes. The oogonia are less than 500 m long. The oospores are dark brown and have reticulate membrane and prominent ridges. The antheridia are 200-300 m in diameter.

Habitat
Nitella mucronata has been found in puddles, ditches and lakes. The water is normally more or less alkaline, oligotrophic to mesotrophic. It can also be found in humic alkaline waters and in brackish water. The species seems to benefit from dredging of canals and ditches. N. mucronata is a perennial species and it is green during the winter. Normally it has fertile plant from July and until September. Ripe oospores, which are dark brown are not common. According to Hasslow (1931) the species is a late-summer to autumn species.
