Comment: Metzgeria furcata is a common liverwort in Trenta valley and elsewhere. It grows mainly on bark of deciduous trees, preferring Fraxinus excelsior. Sometimes it can be found also on rocks, soil or mosses. This find is growing on mosses (see Fig.7). The liverwort is splitting strictly dichotomously and the angle between braches is fairly constant around 80 to 90 degrees. Scattered, irregular hairs on the edges of the thallus (Fig 5.) are also characteristic for this species.
