Crescent-cup Liverwort – Lunularia cruciata



This pale green liverwort forms large branching thalli up to 12mm wide. It is dotted with tiny air pores and has a shiny surface. It is covered in crescent-shaped cups which contain green, disc-like gemmae (reproductive parts), and is the only thallose liverwort to do so. Capsules are rare.

It is often found in gardens and greenhouses and treated as a weed. It particularly likes damp and shady places, and can also be found near the base of damp walls, near water courses, or on shaded soil. Very common and widespread throughout Britain.
