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 interesting but unfortunately its not a clear enough photo to see the details clearly.
Could you see if there were apothecia present (jam-tart like fruiting bodies)? A photo of them and some details of what the roof was made from would be helpful.
I'll get the ladders out and look for jam tarts !
Thanks for the new photo - Aspicilia contorta is a possibilty
Many thanks, I've just been wading through the photos on the British Lichens website and had Aspicilia contorta on my shortlist - mind you I've only got up to Lichens beginning with D !
If its any help to reduce the wading lichens are categorised by their different growth forms here:
Clicking on the tabs for 'Crustose' 'Foliose' etc will get you into each section with thumbnail images that open to an info page with larger photos.
They were photographed in Ireland but the species are found in the UK too.
Thanks for yet another helpful comment - I'll certainly give that website a go.
