RFH3PACB–Liverwort spore capsule. Light micrograph (LM). Longitudinal section through the thallus and sporangium of a liverwort (Pellia epiphylla). The sporangium (spore capsule, upper centre) is enclosed within the thallus case (calyptra). The sporangium is densely packed with spherical spores (green), which are carried away by air currents when the sporangium splits open. Magnification: x20 when printed at 10 centimetres wide.

In the Anthoceroteae it is when mature an elongated two-valved pod projecting from the thallus. In the Riccieae it is a thin-walled ballentirely filled with spores, and, together with the calyptra, depressed in the thallus.In the Marchantieae it is a shortly-stalked ball enclosing elaters as well as spores,and, after it has broken through the calyptra, bursting irregularly or opening by acircular fissure and detaching an operculum.

The basal wall is transverse, as in the Marattiacese, and the formation of the quadrants takes place as usual. The position of the quadrant walls is, however, some
