The largest moss in the UK, marsh hair moss grows in damp woodland and ditches, and on heaths and moorland. It grows relatively tall and often forms large 'cushions' or hummocks. The fruiting bodies appear in summer - the capsules are borne on a long, red stem and covered by 'calyptra' (capsule covers).What to look for
There are at least five species of hair moss in the UK, which are very difficult to tell apart. Marsh hair moss (also known as 'common haircap') is green, with tough, red, wiry shoots bearing narrow, toothed, spear-headed leaves.Where to find

The common name of marsh hair moss is derived from the golden, hairy calyptra of the fruiting bodies, which are very conspicuous.The Wildlife Trusts manage many heathland and woodland habitats sympathetically for the benefit of all kinds of wildlife. Careful grazing with traditional breeds, scrub clearance and coppicing are just some of the ways heathlands and woodlands are kept in good condition.
