Sphagnum angustifolium is a delicate peat moss belonging to the Cuspidata section and can be macroscopically differentiated from other sphagnes due to the clearly long, pointed branch leaves, the small, triangular, blunt-pointed stem leaves and the greenish color. It is called narrow-leaved peat moss and also short-leaved peat moss in German-speaking countries.
Identifying features
The medium-strong plants are mostly yellowish-brown in color, purely green plants appear more rarely. The branches are organized in clusters of four or five, usually 2 or 3 of them stick out.
The epidermis of the trunk is not formed. The scleroderma is hyaline. The small, triangular shaped stem leaves are pointed, have a rounded or frayed tip and are about 1 mm in diameter. The stem-leaf hyalocytes have only a few fibers and pores.
The elongated, lanceolate, 2 to 3 mm long branch leaves gradually taper into a point. When dry, the leaves are only slightly wavy. The branch leaf hyalocytes have smaller, often indistinct pores on the inside and outside. The chlorocytes, triangular in cross-section, are exposed on the outside. On the inside, they are usually enclosed by the hyalocytes.
There is a particular risk of confusion with the deceptive peat moss ( Sphagnum fallax ), whose tufts are straight and clipped. The adjacent branches are longer than the protruding ones. When dry, the branch leaves are only slightly wavy and somewhat narrower than those of the deceptive peat moss. The stem leaves are triangular and slightly rounded at the tip and about as long as they are wide, which also distinguishes Sphagnum angustifolium from Baltic peat moss ( Sphagnum balticum ) and Sphagnum flexuosum . A certain microscopic feature is always the missing epidermis.
Occurrence
Sphagnum angustifolium colonizes oligo- to mesotrophic, medium-acid moors and swampy locations. It has a circumboreal distribution. It is more common in temperate continental regions while it is less common on the coasts. Typical accompanying mosses are the fringed peat moss ( sphagnum fimbriatum called) or Petite peat moss, in bogs the Deceptive peat moss ( sphagnum fallax ), Magellan peat moss ( sphagnum magellanicum ) or reddish peat moss ( sphagnum rubellum ) and fens the Russow-peat moss ( sphagnum russowii ) or Sphagnum teres .
