Crescent-cup Liverwort - Lunularia cruciata

Description

Forms large, pale green, dichotomously branching thalli to 12 mm wide. The shiny, faintly lined surface is dotted with tiny, though quite conspicuous air pores. It possesses crescent shaped receptacles unique amongst thallose liverworts, which contain green, disc like gemmae. When dry, thalli can become yellowish, with inrolled margins, and the reticulations can almost disappear. Capsules are very rare, and are borne on a distinctive, cross like, stalked female receptacle.
