Foliose lichen on Common Oak in hedgerow between farmer's field and Sutton Manor Park (ex-colliery site).
Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
Thanks gardener and other in agreement.
It does look like the other observations for Parmelia sp., however, it also looks like Hypogymnia physodes or Hypotrachyna revolta. I came to the ID using the Bayesian Key on this site. I reckon more info is needed to make a more accurate ID. I'll review it over the year.
