Green granular lichen growing on deciduous twig. Black lecideine apothecia. Possibly Fuscidea lightfootii.
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 for help with the identification. Imagined seeing crustose lichens on rocks on Dartmoor so surprised to see this.
