Oakmoss (Evernia prunastri)

This foliose lichen comprises of divided, flattened but curled, antler-like branches. Strap-like lobes can vary in colour from greenish-grey above to yellow-grey on the upper surface, whilst it is white below.  Green blotches may sometimes be seen on the end of the lobes. Apothecia very rare. Thallus 7 to 10cm long, 1 to 5cm tall.

Found mainly on the branches of oaks and other deciduous trees in sunny areas. Rarely found on conifers. Found in parkland, on wayside trees, and in hedgerows. Widespread and generally common.
