The liverwort Ptilidium ciliare , also known under the German name Behaartes Federchen-Lebermoos , Großes or Sand-Federchen-Lebermoos , is a representative of the leafed liverwort order Ptilidiales . Since the moss seldom forms sporogons , it is presumably spread as a twig or as a fragment in the open landscape by wind or in forests, also attached to animals. The species tolerates prolonged drying out. It belongs to the poikilohydric mosses. The fine hairs allow them to quickly absorb droplets of mist or dew.

Occurrence

The hairy feather liverwort is a characteristic moss of the heather vegetation of sand dune forests. It also grows on humus soil, in coniferous forests (especially in pine stands) and heaths. It is also rarely found on boggy soils, on tree bases and on low-lime silicate rock. In Germany it is currently on the decline. Liverwort is found in the cool, temperate zones of the northern hemisphere throughout Europe, Asia and parts of North America. In Patagonia and New Zealand , it is likely considered a neophytic moss. It can rise above the tree line.

Leaf with 3 ciliate lobes, with 15 to 20 cells at the base of the lobe

features

The hairy feather liverwort grows in lawns or in extensive, flat blankets. The individual plants are copper-colored, brown-green to light green in color and have a characteristic feathery branch. The lobes of the leaflets have characteristic, fine hairs, which are supposed to remind of the structure of feathers. This is why the moss got its German name. The up to 8 cm long stems are relatively loosely leafed and have transversely positioned, overshot flank leaves that are about 2 mm long and half or one third divided into two to three lobes with 15 to 20 cells at the bottom. Each lobe has characteristic eyelashes that are about 0.3 mm long and often have two rows at the base. The transverse sub-leaves are slightly smaller than the flank leaves and also ciliate. Oil bodies are often present at the tip of the stems. Sporogons are rarely trained. The archegonia are then at the end of the main rung or the side branches. The egg-shaped perianth is more or less deeply folded.
