Meesia uliginosa (German Haar-Bruchmoos , Sumpf-Bruchmoos ) is a deciduous moss species from the Meesiaceae family .
features
Meesia uliginosa forms yellowish green lawns that are up to 10 centimeters high in deep areas and often only 1 centimeter high in the Alps. The plants are branched and rust-red rhizoid-tomentose below . The upright to one-sided leaves are up to 3 millimeters long and 0.8 millimeters wide, narrow tongue-shaped to linear and bluntly pointed. The leaf margins are strongly rolled up. The very broad rib ends in the tip of the leaf and shows small outer and larger inner cells in cross section. The leaf cells are square to narrowly rectangular and about 10 micrometers wide. The brownish, slightly curved and blunt-capped spore capsule is lifted up over the moss lawn by the Seta, which is up to 8 centimeters long . Spores are fine papillae, yellowish green and 40 to 56 micrometers in size.
Location claims and distribution
The moss grows in shady, moist to wet and lime or base-rich locations, especially on humus on embankments or cracks in slopes, under crooked wood, on limestone or in flat moors. In the Alps - here it is the most common species of the genus - it occurs frequently to scattered at altitudes of around 700 to 3000 meters. In Germany it used to occur sporadically in the whole area outside the Alps on suitable bog sites, but is now lost, apart from a recent find in the Ore Mountains.
The species is circumpolar worldwide.
