Different coloured funghi
Lots of algea growing on them.
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.
Looks like an old specimen - dried/faded with algae colonising it, but I do agree with your i.d.
