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.
Classic subsp. contorta.
There is a photo of the two subspecies side by side on my website. Both of them abunadant on a concrete wall capping and looking quite distinct (though somewhat reduced in quantity now a lorry has demolished part of the wall).
