Global distributionThis species is found in Norway and the Faeroes to Northwest France.
HabitatConfined to the sublittoral where it grows mostly on small perennial algae and blades of Laminaria hyperborea as an epiphyte, and also on bedrock at depths of 5-30 m. Tolerates moderate to extreme wave exposure.
- Deep pink colour.
- Uninucleate vegetative cells.
- Zig-zag or U-shaped short side branches (carpogonial branches).

Additional informationIdentification of single specimens can be difficult, so if possible a number of thalli should be collected. However, the species is fairly easily distinguished using a microscope.
