Leptogium lichenoides (L.) Zahlbr.


Thallus gelatinous, papery when dry, lobes grey-brown to dark brown, with rib-like wrinkles beneath, margins lacerate to fimbriate with fine, finger-like (not flattened) projections or isidia; apothecia rare. Widespread but probably mostly in the north and west, amongst mosses on rocks, soil and tree-bases.

This species has been confused with L. pulvinatum, which has similarly fimbriate margins but with the fine projections flattened, not cylindrical or finger-like.
