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.
I missed the orange apothecia when I first looked. I'm now "as sure as I can be" that it's Lobaria pulmonaria (sometimes known as tree lungwort). I wouldn't like to name the grey species, though.
The greyish species is another Lobaria - L. scrobiculata. If it were damper it would be more grey-blue.
