Dicranum viride ( Green Fork Teeth moss or green moss spider ) is a moss - kind from the family Dicranaceae .
features
Dicranum viride usually forms small, dense, green to dark green, rust-colored, rhizoid-felted, up to 4 centimeters high lawns or cushions. The whole-margined leaves with a strong protruding rib, drawn out into a long, furrowed, awl-shaped tip for a lanceolate base, are moist, stiff and upright to slightly one-sided, dryly bent to slightly curled; they are very easily brittle, which is why the leaf tips are usually broken off. The lamina cells are almost entirely square to shortly rectangular, with the exception of only a few rows of rectangular cells on the leaf base and the clearly separated leaf wing cells. Spore capsules are quite rare, reproduction usually takes place vegetatively through the broken off leaf tips.
Distribution and location requirements
The moss with subcontinental-montane distribution occurs in Europe, southwest, northeast and east Asia as well as in North America. The European deposits are mainly located in Central Europe. In Germany it is partly quite common, especially in Baden-Württemberg, in the north it is almost entirely absent.
It grows epiphytically in ground and humid forests on the bark of deciduous trees, especially near the ground and on rotten wood, less often on humus or silicate rock.
protection
Dicranum viride is one of the few mosses that are protected under the Bern Convention in Europe. The green besenmoos is also mentioned in Appendix II of the Habitats Directive .
