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.
Something is attacking this. The grey areas are not a shade effect, but more of a death effect.
There are several fungi that parasitise X. parietina, but I don't see the smoking gun.
