Tree lungwort Lobaria pulmonaria

Best Time to See
Habitat Woodland

A beautiful, vibrantly green, leafy lichen.

Its lobes look a bit like the billowing shape of human lungs, hence its name. In fact, because of this resemblance, mediaeval medics used it to treat lung disorders.

Tree lungwort is one of the largest lichens and is an indicator of ancient woodland.

Where to see it

Tree lungwort is found mainly in Scotland, particularly the west coast, where the wetter climate provides the moisture it requires to thrive. Because of air pollution, it is much sparser in the rest of Britain, confined to a few sites in wilder areas, such as the Lake District and parts of Wales.
