Nowellia curvifolia (synonym Cephalozia curvifolia (Dicks.) Dumort.) Is a liverwort species from the family Cephaloziaceae and belongs to the group of leafed liverworts. German-language names are Krummblattmoos or Krummblatt-Lebermoos .
features
Nowellia curvifolia is a very delicate moss and forms yellow-green to red-brown, flat coatings on the populated substrate. The prostrate plants are cord-shaped and up to 1 millimeter wide. The loosely protruding and overlapping leaves are entire, somewhat hollow, asymmetrical and end in two hair-shaped, 4 to 10 single-row tips. At the lower rear edge of the leaf there is a sack-shaped leaf flap. Lower leaves are only present on female gametangia stands, otherwise they are absent. The leaf cells in the middle of the leaf are around 20 to 35 µm in size, have yellowish, thickened cell corners and numerous tiny oil bodies .
The moss species is diocesan , sometimes also monocy . The perianthia, which are often formed, are long, longitudinally folded at the top and have a ciliate mouth. The female bracts are two-part and toothed. Spores are papilose, red-brown and 8 - 9 µm in size. Spore ripening time is in spring. Brood bodies used for vegetative reproduction are occasionally present at the leaf margins or tips; they are yellowish green, spherical and 14 to 19 µm in size.
ecology
Nowellia curvifolia grows in shady to partially shaded locations in forests on damp, rotten wood. Lime-free rocks or, in oceanic climatic regions, peaty or sandy-rocky subsoil are rarely settled. Frequent accompanying mosses are Blepharostoma trichophyllum , Herzogiella seligeri , Hypnum cupressiforme , Lophocolea heterophylla and Riccardia palmata .
distribution
The general distribution is sub-oceanic-montane. In Europe it is particularly widespread in the mountains, in the lowlands it occurs in spruce forests. In the far north of Europe it is absent, towards the south it occurs as far as northern Spain, Corsica and the Balkans. There are other occurrences in Asia, North, Central and northern South America.
