The white leaf tips make this moss quite distinctive. It grows in small tufts of narrow, upright shoots up to 1cm high, usually with abundant capsules. The leaves are 2.5-4mm long, and the capsules are 1.5mm long. Ripe capsules are light brown and slightly furrowed when old and dry.
Found on trees and shrubs, but also on rocks, concrete, brick walls and other inorganic structures. Very common and widespread throughout Britain.
