Comment: Ctenidium molluscum is another common, widespread and beautiful moss, found in many calcareous habitats. One can find it in woods, cliffs, boulders, on soil, rocks and also in grassland. It is a notoriously variable species sometimes posing difficulties in determination if not in its typical form. The tips of the branches are typically hooked and lighter than the rest of the plant. Shots are usually two to three cm long, but can be also longer, particularly when hanging on vertical surfaces. Leaves on branches are all curved, about 1 mm long and have no central nerve. Stem leaves are not much longer but significantly broader.Ref.:(1) Ian Atherton, Ed., Mosses and Liverworts of Britain and Ireland - a field guide, British Bryological Society (2010), p 812. (2) V.
