Pushing on today into the blackthorn a bit deeper than the previous scallop we came upon a small area of blackthorn under a couple of small oak trees that is almost completely covered in lichen. Now lichen id is not really my thing but I think it is Ramalina farinacea or Cartilage Lichen. We are not going any further in so this will not be disturbed at the moment.
We also found a fleece tree ripe for picking, so helped ourselves.
