Heart-leaved Spear-moss - Calliergon cordifolium

The erect, little branched shoots of this medium sized to large moss are green (or brown below) and may reach 15 cm long or more. Stem leaves are 2 to 2.5 mm wide, more or less egg-shaped, somewhat heart-shaped at the base, and blunt or rounded at the tip. They often spread outwards from the stem, and have large patches of colourless cells which extend across the whole of the leaf base. However, these are not sharply marked off from the adjacent leaf cells, and are inconspicuous. Branch leaves are smaller and narrower. Capsules are rare.

Marshes, damp places and wet woods, especially in lowland areas.

All year round.

Widespread and fairly frequent in Britain.

Fairly frequent in Leicestershire and Rutland.
