A lush green spreading liverwort, where the gametophytic thallus is dichotomously branched, meaning that the shoot apex splits exactly in half during branching producing two equal branches. The liverwort is dioicious, meaning male and female gametes are formed on separate plants. The male structures are in purplish bumps near branch tips. The female structures are like tiny umbrellas growing to up to 10cm tall. Width 1 to 1.5cm. Length 20cm.
Found on damp, shaded stonework or rock structures, and in ditches, near streams and in damp woodland, forming large spreading carpets covering the surface. Common and widespread throughout Britain.
