The segments are either fully corticate or ecorticate at the internodes which gives a banded appearance.ReproductionThe gametophytes are dioecious or monoecious. Spermatangial sori occur on young axes and cystocarps contain numerous carposporangia. The tetrasporangia occur in whorls on the younger branches.HabitatEpiphytic on other algae in the littoral zone as well as the sublittoral.DistributionRecorded from the coasts of Great Britain, Ireland, France, the Netherlands, Norway, Portogal, Spain, and Morocco.
