Bryum schleicheri ( Schleicher's pear moss ) is a deciduous moss from the Bryaceae family .
features
Bryum schleicheri forms soft, loose and swelling, yellow-green lawns three to ten centimeters high. The sparsely rhizoid felted stems are loose and protruding at the bottom, dense and puffy-leafed at the top. The leaves are egg-shaped, hollow and short-pointed or bluntly rounded, with the leaf base clearly sloping down on the stem. The flat leaf margins are clearly set off with three to five rows of narrow, elongated cells. The leaf vein extends to the tip of the leaf or emerges as a short spike tip. The lamina cells in the middle of the leaf are thin-walled, rhombic and about 25 to 40 µm wide.
The diocesan moss rarely produces fruit. The seta is about four to six centimeters high and crooked at the top with short hooks, the pendulous capsule short and broad, pear-shaped.
Location claims and distribution
Bryum schleicheri grows in spring corridors and on streams, in both lime-poor and lime-rich, but light-rich locations.
In Central Europe it is particularly widespread in the Alps, where it occurs mainly in subalpine and alpine locations. There are other occurrences in the low mountain ranges, but mostly much less common.
Due to taxonomic uncertainties, the overall distribution is partly unclear. There is information on occurrences from many parts of Europe, from Asia, North Africa, North and South America, which, however, needs to be checked.
