Cladonia glauca (images of British lichens)

Podetia ash-grey, slender, commonly unbranched, taperered to a point, usually with a longitudinal fissure that may be hidden by soredia, ecorticate and greyish farinose-sorediate almost to base, usually sparsely squamulose in lower part, basal squamules small; apothecia brown, rare. Widespread but local, on acid, rotting wood, heaths and drying peat surfaces; easily confused with similar species if critical features are not checked.
