Pellia is a genus of thallose, i.e. leafless liverworts . It is named after the Florentine lawyer Leopoldo Pelli Fabbroni, a friend of the describer Giuseppe Raddi . Pellia is the only genus in the Pelliaceae family , which in turn is the only family in the Pelliales order .
features
The thalli of the mosses of this genus are fleshy, irregularly forked and not lobed or slightly lobed at the edges. They have an indistinct, multi-layered midrib. The underside of the midrib is flat and bulging and covered with numerous light brown rhizoids. Towards the edges, the thalli are thin, single-celled and more or less transparent. The thallus cells are thin-walled and contain few or numerous oil bodies .
The species are diocesan or monocy . Antheridia are sunk in small hollows on the upper side of the thallus along the midrib. Archegonia are also located on the top of the thallus, they are surrounded by a scale or egg-shaped shell. The fleshy kalyptra is enclosed in the shell or clearly towers above it. The long seta has a spherical spore capsule that opens with four flaps. The elater carriers are attached to the base of the capsule as a conspicuous brush-like tuft. The large, multicellular spores are ellipsoidal to spherical and smooth to slightly papillary.
species
The small genus Pellia comprises only 5 to 6 species worldwide, of which the following 3 occur in Europe:
