(Cephaloziella turneri)
This is one of our most beautiful liverworts and finding it is always a thrill. Its leaves are about 0.25 mm long, and have 2 slightly unequal-sized lobes, each armed with many teeth that are clearly visible through a hand lens. Its slender (less than 0.5 mm wide), green shoots creep among small mosses or sometimes form dense little patches, and are often tipped with pale gemmae.
