Liverwort  (Cephaloziella massalongi)

In Great Britain this liverwort is known only from the south-west of England and north Wales, and is locally abundant at a number of sites in Cornwall and Devon (1). Elsewhere it has a wide distribution, occurring in north-western Europe, where it is classified as rare, and in the southern Appalachian Mountains in the USA (1).

Typically grows around copper mines or other copper-enriched habitats in damp acidic soil, on walls, rocks, and mine-spoil (1).
