Greeny grey fruiting cups. Pink edges on some.
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.
Not sure what this is but it's a crustose lichen (possibly a Leconara), not a Cladonia. I think you might be confusing the neat, round apothecia here for the leafy, more irregular squamules of C. pocillum, and I have to admit that they don't look too dissimilar!
Edit: the pink bits are interesting.
