The velvet short rifle moss ( Brachytheciastrum velutinum , syn .: Brachythecium velutinum ) is a very rich in shape, relatively common in Central Europe, which loves particularly shady places. Its leaves are no longer than 1.5 mm.
Occurrence
The moss colonizes both earth and bare rock. It is not uncommon to find it on tree bases and their roots. It is a lime-avoiding deciduous moss, which can also grow on branches of trees, which are then mostly in heavily polluted urban areas. B. velutinum is more drought tolerant than Brachythecium rutabulum . It is widespread from the lowlands to the high altitudes of the Alps and occurs only in the temperate latitudes of the northern hemisphere.
Identifying features
The velvet short rifle moss forms soft, yellow-green to brownish colored, relatively loose, velvety-shiny lawns. Its prostrate, creeping trunks are irregularly pinnate and about 5 to 10 cm long. The only up to 1 mm long stem leaves are narrowly eilanzettlich shaped and gradually pointed at the front. They also often appear weakly wrinkled and are often somewhat one-sided. Your leaf margin is serrated. The leaf vein reaches half or two thirds of the leaf length. The branch leaves, on the other hand, are up to 1.5 mm long, narrower and longer and are sawn around. Your midrib emerges as a short spine on the back of the leaf.
The rough seta is up to 2 cm long and arises from the lateral short shoots ( pleurocarp ). The egg-shaped, reddish-brown colored capsule is strongly inclined to upright and curved when empty. The kalyptra is short conical. Spores ripen in winter into spring.
