Plagiothecium undulatum , also known colloquially as Wavy-leaved Schiefkapselmoos or Wavy -leaved Schiefbüchsenmoos , is a conspicuously white-green deciduous moss species that is common in the montane and subalpine areas of Europe.
description
These are quite robust mosses, the stems of which can reach lengths of up to 15 cm. As a rule, however, the white-green, clearly visible part is 3 to 4 cm long. The plants are very shiny.
The leaves of the plants are flattened and swollen at the same time, which means that the leaf surfaces are more or less in one plane, but are curved in such a way that the stems have a flattened, worm-shaped appearance. The leaves themselves are clearly wavy across the front. These characteristics distinguish Plagiothecium undulatum from all other mosses. The leaves are slightly asymmetrical and oval-lanceolate in shape. The leaf margin is finely indented at the tip. There is a short double rib. The leaf wings run down the stem as a short, very narrow band.
The moss is dioecious . It rarely forms capsules.
Distribution and location
It grows in the temperate areas of North America , especially in the Pacific west, as well as in the more oceanic part of Europe up to Asia Minor .
The lime-avoiding moss grows on acidic forest soils, preferably in mountain forests and on log heaps, as well as in heaths and on bog soils (peat). In suitable locations, it often forms bulk stocks and can form ceilings of square feet.
The moss provides good protection against erosion on slopes. In the plain, however, it can lead to waterlogging and promote the formation of raw humus , because the densely packed leaves require a very large amount of water conduction and storage.
