Identification notes
There is rarely any doubt identifying this liverwort in the field. It is a plant of usually vertical limestone surfaces on low cliffs in sheltered woodland, often in association with Marchesinia mackaii. The mats of narrow lobed thalli with bifurcate branching are similar to other species in the genus, but the surfaces are densely felted and give a dry appearance unlike any other species. A hand lens will confirm an opaque thallus smothered in hairs.
