This moss has regularly branched, roughly triangular pinnate shoots 1-2cm long. Robust woodland forms have bi- to tripinnate patterns and are larger. Stem leaves are 1-5mm long, and differ in shape from branch leaves. The stem leaves are triangularly heart-shaped with a fine elongated tp which often turns outwards. Branch leaves are about 1mm long, egg-shaped with a shorter tip, and finely toothed with a single nerve. The capsules are fairly frequent and are about 2mm long with a beaked lid.
It is found on banks, in turf, on soil in woodland, on logs and at the base of trees and on branches. It may also appear in lawns. Common and widespread throughout.
