(Racomitrium lanuginosum)
Racomitrium lanuginosum grows as "large cushiony mats". Its stems are up to 12 centimetres (4.7 in) long and irregularly branched. The leaves are 3-5 millimetres (0.12-0.20 in) long, 0.6-0.9 mm (0.02-0.04 in) wide, lanceolate, pointed and with a strong midrib. They end in a long, thin hair-point, with teeth along both sides pointing 40--90- from the axis of the leaf. The hyaline (transparent) margins of the hair-point are decurrent along the sides of the leaf.
