Plagiochilaceae (German mussel mosses ) is a family of liverworts from the order of the Lophocoleales .
features
The plants are green to brownish, prostrate to erect or drooping, in some species tree-shaped. The branches usually arise laterally, rarely on the underside (ventral) of the trunks. The foliage is clearly flattened, the undershot leaves have entire margins, fringed or toothed and usually run down the stem. The leaf cells are usually thin-walled and contain 4 to 12 oil bodies . Sub-leaves are usually present, but are usually small.
The gender distribution is mostly diocesan . The perianth is cylindrical or bluntly triangular at the bottom, compressed at the top and the mouth is bent laterally. The capsule flaps have 4 to 10 layers. The spore size is between 12 and 40 micrometers.
