2 varieties of flat, leaf-like lichen which were found on the top and side of a west, facing red brick wall no older than 12years.
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.
The yellow lichen is Xanthoria parientina and the whitish-grey one is Physcia adscendens.
The very small darker grey lobes above the Physcia are probably Phaeophyscia orbicularis and the small apothecia (jam-tart like fruits) with white margins are a species of Lecanora.
Thank you very much for that Jenny. Very helpful.
