Pedinophyllum interruptum (German Interrupted Flat Leaf Moss ) is a liverwort species from the Plagiochilaceae family .
features
The plants grow prostrate in olive-green to brown-green lawns or between other mosses. The shoots are usually richly branched, 1 to 4 inches long and 2 to 3 millimeters wide. The flank leaves, which hardly run down the stem, are elliptical to rounded, rectangular or slightly bulged at the top. At the end of the rung they are often bent together like praying hands. The leaf cells are thin-walled, the corners hardly thickened triangular; the cell size is 20 to 35 micrometers, smaller on the edge of the leaf and larger in the middle of the leaf. There are 4 to 8 grape-shaped oil bodies per cell . Young shoots usually have small two to three-lobed sub-leaves.
The gender distribution is autocratic . Gametangia stands are at the end of main or secondary branches. The male bracts are smaller than the flank leaves and sack-shaped at the base, the female are similar to the flank leaves. Perianthia are often present, half of them protrude from the bracts, are flattened at the top with a truncated, whole-margined to somewhat coarse-toothed mouth. The spore size is 15 microns.
Location claims and distribution
Pedinophyllum interruptum grows on shady, moist limestone or calcareous rocks in humid areas, where steeply sloping to overhanging rock surfaces are preferred.
European distribution areas are in the central part, here to the south to northern Spain and northern Greece, to the west to England, Scotland and Ireland, to the north to the southern edge of the north German lowlands and to the east to Bulgaria, Romania and the Ukraine. There are other occurrences in the Caucasus , South Caucasus , Western Asia, Algeria and Eastern North America .
In Germany the species is quite common in the Alps and the Jura, but is completely absent in the northern German lowlands. In Austria, it is particularly widespread in the northern and southern Alps and the flysch zone and is often common, otherwise less often or is absent in certain areas.
