Tortella tortuosa is a moss -Art from the family pottiaceae . German names are Gekräuseltes Spiralzahnmoos or Gewelltes Spiralzahnmoos . Synonyms are Tortula tortuosa Hedw. and Barbula tortuosa (Hedw.) F.Weber & D.Mohr.
features
Tortella tortuosa forms dense, often extensive, cushion-shaped lawns; these are yellowish green to green and in the lower part brownish and rhizoid-felted. The densely leafy shoots are forked and about 2 to 6 centimeters high.
The leaves are linear-lanceolate, very long and finely pointed, mostly clearly wavy. They have a single-layer lamina and flat, crenulated leaf margins. The leaf vein is shorter or longer emerging.
The lamina cells are elongated, rectangular, hyaline and smooth on the leaf base. They are sharply demarcated from the rounded, green and strongly papillary cells in the upper part of the leaf, the border being roughly V-shaped. The upper side of the leaf vein is covered at least in places with rounded, square, papillary cells in the middle of the leaf, the underside has only long, narrow and smooth cells along its entire length.
The moss is diocesan . The upright seta is 1.5 to 3 centimeters long, the spore capsule elongated-ovoid to cylindrical and upright to slightly curved, the lid long beaked. The thread-like peristome teeth are spiraled.

Location claims and distribution
Tortella tortuosa grows preferentially on calcareous rock in shady to partially shaded and fresh to moist locations, less often it colonizes drier places or soil.
It is particularly widespread and frequent in the limestone mountains. In the Alps it rises above the tree line and even as far as the nival level. It only occurs sporadically in the lowlands.
It occurs worldwide in Europe, Asia, North Africa, North and South America and the Antarctic.
