Foliose lichen, Woodland, Attenborough Nature Reserve, Nottinghamshire
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.
I'd need a clearer (more zoomed in) photo to be sure, but the orange coloured lobes (leafy bits), round fruiting bodies and general habit of this suggest this species. It's very common on trees, particularly elder, or where there is high levels of nitrogen in the atmosphere. See http://www.opalexplorenature.org/LichenGuide for some more guides.
