Weissia multicapsularis - with its curious name, this moss forms small patches on the ground and on hedge banks. It is mid-green to yellowish and produces small shoots often under 1cm tall. The species is found at two locations on the south coast of Cornwall: Talland Bay (3–4 subpopulations) and Portscatho (3 subpopulations). It was once recorded in France, however now it is considered extinct. It is threatened by a lack of grazing animals, competition from other plants and fertilisers. The species is listed as Critically Endangered because it has such a small range and tiny population, all outside of protected areas, and is highly sensitive to changes in land-management practices. The species could easily disappear from Cornwall.
