Tetrasporophyte plants occur as far north as Shetland but not eastern Scotland. Gametophyte plants (red on the map) are described as present in south-west England and in western Ireland but occur sporadically and may be absent for many years.
Outside of the British Isles this red alga extends to the Atlantic coast of France, Spain and Portugal into the Mediterranean. It originated in the Pacific and Indian oceans.
The sexual (gametophyte) plant is found in the shallow sublittoral or in deep littoral pools attached to other algae by its barbed axes. The asexual (tetrasporophyte) plant is typically found sublittorally and is epiphytic or sometimes free-living.
