Silver-moss - Bryum argenteum

    Alt Name
    Silver Thread-moss
    Description

    This is the most recognisable of all British mosses. B. argenteum forms pale green or almost white, compact tufts or patches which look shiny and silvery grey when dry. The crowded shoots are usually less than 1 cm tall, and the rounded, concave leaves (0.75 to 1.25 mm long) cause the shoots to look smoothly cylindrical, hardly altered when dry. The nerve ends well below the leaf tip. The shortly oblong, pendulous (or rarely nearly horizontal) capsules are small (about 1.5 mm long) and borne on a short seta (about 1 cm long). They are usually produced between autumn and spring.

    Habitat

    Found in disturbed habitats which may become very dry and are usually rich in nutrients such as nitrates. These include soil on and by paths (including cracks between paving slabs), roads, in arable fields, on waste ground and railway lines. It may also be found on stone rather than soil, as on walls, buildings, roofs, and concrete and tarmac. Habitats less influenced by man include sand dunes, eroding banks of streams and rivers, and unstable soil on lowland cliffs.
