features
Barbilophozia barbata forms brown-green to olive-green, often extensive covers or lawns or grows as single plants between other mosses. The ascending and often branched above plants are 5 to 8 centimeters long and 3 to 5 millimeters wide. Their underside is densely covered with rhizoids.
The flank leaves, spread out on both sides of the stem, are densely arranged and arranged undershot, are roughly the same width as they are long and up to about a quarter of the leaf length, usually divided into 4 triangular, bluntly pointed lobes, the two outer lobes being slightly narrower than the middle ones. Lower leaves are missing or are only small and only present at the end of the stem.
Leaf cells are 20 to 25 µm in size and have slightly thickened cell corners. There are around 5 to 6 oil bodies per cell .
The moss species is diocesan . The large perianth is club-shaped, deeply wrinkled in the upper third and contracted at the mouth. Brood bodies are very rare.
ecology
Barbilophozia barbata grows in moderately shady, drier to moderately fresh, mostly lime-poor locations. Rock sites, but also tree roots, earth and humus as well as walls are preferred. It is fairly widespread in middle mountain areas, but quite rare on the plains. In higher mountain areas this species is replaced by Barbilophozia lycopodioides .
distribution
The moss is distributed in the circumboreal region and is found in Europe, Iceland, Siberia, Japan, North America and Greenland. The European occurrences extend from northern Europe to northern Spain, Italy and Bulgaria.
