Marchantia (order Marchantiales) A genus of thallose liverworts. M. polymorpha is a common species in Britain. It is immediately recognizable by the presence on the upper surface of symmetrical, cupshaped structures containing small discoid gemmae. The plant is particularly conspicuous when fertile; the male reproductive structures resemble miniature mushrooms, while the female structures are stalked with many radiating, spokelike lobes at the top of the stalk. It is common in gardens, on paths, flowerpots, etc., and is also found on moors, heaths, river banks, etc.
