Lobaria virens (images of British lichens)

Thallus lobes large, bright green and somewhat lustrous when wet, drying to pale green-grey or grey-brown, surface smooth or becoming wrinkled in older parts, lacking isidia, soredia or cephalopodia but apothecia may remain as undeveloped apothecial initials on the thallus surface. On sheltered, deciduous tree bark, rarely rocks, in parkland and old forest, largely restricted to unpolluted areas of western Britain, formerly more widespread.
