Springy Turf-moss – Rhytidiadelphus squarrosus

Springy Turf-moss – Rhytidiadelphus squarrosus

The shoots of this extremely common moss may be 10 to 15 cm long, and are distinctive in the way the tapered part of the 2 to 2.5 mm long leaves bend back at a right angle to the base so that they spread out and away from the stem in all directions, giving shoots a star-like appearance. The broad leaf base completely sheathes the red stem so that it is only visible through the leaf bases. The leaf has lightly toothed margins and a short, double nerve. Capsules are generally uncommon. Alternative names: Square Goose-neck moss Habitat: R. squarrosus is a ubiquitous species of unimproved or semi-improved grassland, including lawns. Where the grass is short, either through mowing or grazing, it can form extensive, almost pure swards. It is…

Grey-cushioned Grimmia (Grimmia pulvinata)

Grey-cushioned Grimmia (Grimmia pulvinata)

This is the commonest British Grimmia, and forms round, almost furry, grey cushions about 1 to 2 cm tall. The narrow leaves are 3 to 4 mm long, nerved to the tip, with recurved margins. An important character is the leaf tip, which is abruptly contracted into a long hair point, which may be almost as long as the leaf blade. Oval capsules usually abound, bending back into the cushion on an arching seta (note, however, that when old and dry, the seta straightens and the capsule is held erect); the lid of the capsule has a long beak. In moist conditions, cushions appear dark green, the densely arranged leaves spread away from the stem and the hair points are only moderately conspicuous. When dry, the leaves fold together, with…
