The pale lip cup moss ( Chiloscyphus pallescens ) is a prostrate liverwort . Spore ripening usually takes place in spring. However, this happens very rarely. The species is currently declining slightly due to the destruction of wetlands .
Identifying features
The pale lip cup moss forms pale yellowish-green to brownish-green transparent lawns or grows occasionally between other mosses. Individual plants are up to 8 cm long and about 3 mm wide. The slightly crooked, sloping flank leaves are more or less rectangular, half longer than they are wide, and are more often slightly edged at the tip. The slightly thickened cells of the flank leaves are about 40 to 70 µm long and 30 to 45 µm wide in the middle of the leaf. They contain 1 to 15 oil bodies per cell. The lower leaves are characteristically deeply split into 2 long, thin lobes and are usually slightly curved back. There is a risk of confusion with other leafy liverworts such as B. Lophocolea heterophylla , Plagiochila porelloides , Pedinophyllum interruptum or Jungermannia leiantha , all of which, however, have not so deeply split sub-leaves. Chiloscyphus polyanthos differs in its dark green, opaque color and the smaller flank leaf cells.
Occurrence
The pale lip cup moss colonizes fresh to wet, lime-rich, base-rich to neutral, shady to light-rich locations. It grows on loamy, clay, sandy or humus-rich soil in fens, on wet meadows , but also on roadsides, in ditches, on rotten wood, on rocks that have been trickled over, in spring corridors and at the edges of bodies of water. Liverwort is often associated with Bryum pseudotriquetrum , Calliergonella cuspidata , Plagiochila porelloides , Plagiomnium undulatum or Rhizomnium punctatum . It is widespread across Europe as far as Iceland and western Russia. It can also be found in parts of Asia, North Africa, and North America.
