Sphagnum magellanicum is a peat moss belongingto the genus Sphagnum , Section Sphagnum, and iseasily recognizable by its reddish color and the strikingly large leaves. It is mainly called “Magellan's Peat Moss” or “Middle Peat Moss” in German-speaking countries. It was developed by the members of the Bryological-Lichenological Working Group for Central Europe e. V. (BLAM) voted Moss of the Year 2016.

features

Sphagnum magellanicum forms plants up to 20 cm long, which can be dull dark or bluish red, purple to deep purple or carmine red in color and whose red color is caused by sphagnorubine . Occasionally, greenish plants also appear. They always grow in cushions or form bulbs. 4 to 5 branches come together in clusters, from which 2 or 3 branches protrude. The other hanging branches are close to the trunk.

The weakly fibrous, thin-walled epidermis of the trunk is usually four-layered, with the outer walls usually having 1 or 2 (rarely up to 4) small holes. The scleroderma is reddish, reddish brown, or purple. The flat, almost rectangular, tongue-shaped stem leaves lie close to the carmine-red stem and have no wing cells.

The hollow, lanceolate branch leaves run out into a broad, rounded tip. They are usually tiled on the branches. They are seldom slightly protruding. The hyalocytes have large, round pores on the inner surface of the leaf near the lateral edges. On the outside, the pores stand together in twos or threes. The small, elliptically shaped chlorocytes are usually smooth, appear centered in the cross-section of the branch leaves and are completely enclosed by the large hyalocytes.

There is actually only a risk of confusion with reddish forms of Sphagnum palustre . In the cross-section of the branch leaves, however, it can be clearly distinguished by the centered position of the chlorocytes.

Distribution and location

Sphagnum magellanicum is circumpolar and occurs throughout Central Europe. The peat moss is characteristic of the central areas of intact, ombrotrophic rain bogs , where it grows or forms on so-called bulten . Today it is particularly widespread in not excessively drained raised bog remains. It is rarely involved in the formation of vibrating lawn . Its pH optimum is in the very acidic range between 2 and 4.5. In addition, the mean peat moss can be found in strongly acidic intermediate bogs and in bog forests. The peat moss can withstand a certain amount of shade, but then mostly remains green. It prefers evenly moistened peat soils and avoids areas that are flooded for longer. It is relatively insensitive to temporary dehydration and can regenerate.

The middle peat moss is the characteristic species of the plant communities of the raised bog societies (Oxycocco-Sphagnetea). Typical companion mosses are the reddish peat moss ( Sphagnum rubellum ), the narrow-leaved or short-leaved peat moss ( Sphagnum angustifolium ), the deceptive peat moss ( Sphagnum fallax ), the brown peat moss ( Sphagnum fuscum ) or Girgensohns Torfmoos ( Sphagnum fuscum ).

Hazards and protective measures

Sphagnum magellanicum is endangered by habitat destruction.

At European level, like all peat mosses, the Fauna-Flora-Habitat Directive (FFH Directive for short) provides the option of taking protective measures that can regulate extraction or use (Appendix V) and prescribe the establishment of protected areas ( Appendix I).

In German federal law, the species - again like all peat moss - is listed in Appendix 1 of the Federal Species Protection Ordinance - BArtSchV for short - and thus placed under special protection. The Federal Republic of Germany assesses the species nationwide in hazard category 3 as endangered.
