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.
It's a common problem with many digital cameras that green and yellow-green in lichens is poorly registered and the photo is too grey.
It's most obvious with species with yellowish tints, such as Lecanora sulphurea, Xanthoparmelia conspersa, but it is a problem with Ramalina too.
Thanks, Alan, for ID confirmation and comments.
