Identifying features

Dicranum montanum forms dense, fresh to yellowish green cushions. The individual, up to 5 cm high plants have a dense, brown felt of rhizoids . The dry curled to twisted leaves are curled on one side when moist. They run into a long, deeply toothed awl tip and can be up to 4 mm long and 0.4 mm wide. The leaf vein ends in the leaf tip and takes up about 1/5 of the leaf. The thick-walled, non-stippled lamina cells are oblong and rectangular in the middle of the leaf and about 25 to 50 µm long and 7 to 11 µm wide. In the tip of the leaf, the cells are significantly shorter to sub-square. The inconspicuous leaf wing cells are somewhat bloated.

Occurrence

Dicranum montanum is a common, epiphytic moss, which mostly colonizes the bark of beech, pine and birch trees. It prefers acidic, nutrient-poor and lime-poor substrate. It is particularly common in forests, but is also found on rocks. Frequent accompanying mosses are Dicranum scoparium , Hypnum cupressiforme or Tetraphis pellucida . The moss is distributed in a circumboreal manner. In Europe and Germany it is one of the most common epiphytic mosses on trees, which is relatively insensitive to air pollutants.
