Recorded distribution in Britain and IrelandTolypella nidifica is restricted to two sites in Orkney and the Outer Hebrides. Extinct populations are recorded from five sites: Norfolk, Suffolk, Orkney and Shetland. Also known from three sites in Ireland: Counties Down, Antrim and Londonderry.
Global distributionEuropean populations are confined to the coasts of northern Europe. Frequently in the Baltic, with scattered records from around the North Sea and northern Norway. Also recorded from Australia and New Zealand.
HabitatGrows in sandy substrata with some silt, in ditches, pools and lakes, commonly at depths above 2.5 m, although may be found down to 10 m. Thought to prefer oligotrophic (nutrient poor) waters. Often found in association with Ruppia species, seagrass (Zostera marina) beds and other brackish water stoneworts including Lamprothamnium papulosum, Chara canescens and Chara baltica. The optimum salinity for growth of Tolypella nidifica is thought to be 15 ppt.
- Dark brownish-green coloured stonewort.
- Up to 20 cm in height.
- Much-branched species with incurved branches forming bird's nest structures.
- Branchelets have blunt tips.
Additional informationThe sexual structures of Tolypella nidifica are over 0.5 mm in diameter, much larger than the clustered stonewort Tolypella glomerata, and unlike the latter species, the spore is reddish in colour (Bryant & Stewart, 2002).
