[britishbryologicalsociety.org.uk] Description: This quite bulky species forms dense, dark green patches 1 - 4 cm tall. The leaves are recurved when moist, and twisted when dry. On well-grown stems, the 5 - 6 mm long leaves grow in tufts rather than continuously up the stem. This is best seen in dry plants where the tufts look like little knots up the stem, which is crowned by
a bud formed from twisted leaves. Individual leaves have sides that are distinctly constricted around the middle and recurved for about three-quarters of their length. The tip is rounded and the nerve is excurrent in a long, silvery, toothed hair point.
Upright, cylindrical capsules are common. (link added by Mary Ann Machi)
