Sciuro-hypnum starkei (synonym Brachythecium starkei (Brid.) Schimp.) Is a deciduous moss species from the Brachytheciaceae family . The German names include : Starkes Neuhaarblattmoos , Berg-Schweifchenastmoos , Berg- Kurzbüchsenmoos .

features

Sciuro-hypnum starkei forms green and slightly shiny lawns. The prostrate trunks, which adhere to the substrate with clusters of rhizoids, are more or less regularly pinnate, the protruding branches are arched. Stem and branch leaves are differently shaped and protrude dry and wet to horizontal. The stem leaves are drawn out rather suddenly from a broad triangular, heart-shaped base into a fine point, which is sometimes twisted; they are not or hardly wrinkled, the edges finely serrated, the leaf base on the stem runs down far. The rib ends in the upper half of the leaf. The lamina cells are more or less worm-shaped in the middle of the leaf, and rectangular in the well-delimited leaf wings. The smaller and narrower branch leaves are eilanzettlich, sharply pointed and the edges sawn to serrated.

The species is autocratic (antheridia and archegonia on different branches on the same plant). It is often fruitful and the spores ripen in winter. The 10 to 15 millimeter long Seta is rough, the horizontal capsule is high back, the lid is conical. The finely papillary spores are 14 to 18 micrometers in size.

Similar species

The species is very variable and morphologically stands between Sciuro-hypnum oedipodium and Sciuro-hypnum reflexum . But it can also be confused with Brachythecium rutabulum .

Location claims and distribution

The moss grows mainly on an acidic base in partially shaded to shady areas in montane to subalpine locations on the bottom of trees, on still slightly rotten cut surfaces, especially of spruce and beech, on dead wood, humus and on silicate rock.

In Germany, Austria and Switzerland it is widespread and often common in the silicate mountains, but rarely or absent in the limestone areas and in the plains. Worldwide there are deposits in Europe, Asia and North America.
