Status in Britain: Common

A very common moss occurring in a wide variety of habitats, usually where there is some calcareous influence. In dune-slacks it often forms continuous carpets, frequently associated with willow, rushes or coarse grasses. A characteristic feature is that the tips of the shoots are shaped rather like spear-heads. The leaves taper from a wide base to a blunt, rounded tip, have no nerve, (other species of Calliergon do have a nerve) and have distinct auricles at their basal corners
