Summary

Description

A small (up to 10 cm tall) dark brown to red alga. The thallus is conspicuously constricted giving a segmented appearance. Starting almost at the base, many branches grow out of each constriction, the bead-like segments becoming gradually smaller towards the tip of the branch. The plant is very shiny and the tips of branches may be bleached pink or orange.

Recorded distribution in Britain and Ireland

Lomentaria articulata is found all around the British Isles with plants from the south and west of Ireland tending to be larger than those found elsewhere.

Habitat

Found on rocks and in pools on the middle and lower shore, particularly in shady places, under other algae and overhangs. It is found sublittorally to depths of at least 18 m and exceptionally large, luxuriant plants have been found growing on Laminaria hyperborea stipes.
