Pellia epiphylla

Pellia is a genus thal solver, ie non- exfoliated liverworts. It is named after the Florentine lawyer Leopoldo Pelli - Fabroni, a friend of the describer of Raddi. Pellia is the only genus in the family Pelliaceae, this in turn is the only family of the order Pelliales.

Features

The thalli of the mosses of this genus are fleshy, irregularly forked and non-or weakly lobed at the edges. They have a vaguely delineated, mehrzellschichtige midrib. The underside of the midrib is flat bulging and covered with numerous light brown rhizoids. Against the edges to the thalli are thin, einzellschichtig and more or less transparent. The ones begin are thin-walled and contain few or numerous oil bodies.

The species are dioecious or monoecious. Antheridia are sunk on the Thallusoberseite along the midrib in small cavities. Archegonia are also located on the Thallusoberseite, they are surrounded by a scale-like or egg-shaped shell. The fleshy Kalyptra is enclosed in the envelope or stands out in this clear. The long seta carries a spherical spore capsule, it opens with four flaps. The Elaterenträger are attached at the base of the capsule as striking brush -like tuft. The large, multicellular spores are ellipsoidal to spherical and smooth to slightly papillose.
