On acidic igneous boulder in mountain woodland.
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.
British books treat C. cervicornis and C. verticillata as subspecies, but there is recent Dutch work that separates them as species and my own experience supports their treatment.
I wonder Alan if this one is tiered enough (if that is that a criterion?) - I spent a LONG time over the name on mine here
Just for you!
One has to look at the photographs here quite carefully to see tiers at all. I agree that C. verticillata usually has more tiers, but the Dutch work I mention has shown that number of tiers is not totally reliable.
Here we have rather poorly developed, montane material. My ID remains "It's likely to be this, but I can't be certain", but I stand by my previous comments.
Inerestingly (?) the photo is not unlike the 3rd species of the group, C. pulvinata, but rarity and ecology seem to rule it out (Teesdale is not noted for its acid, coastal sands). After some misgivings I am happy it is NOT C. pulvinata, and the podetia are too neat and the basal squamules are too little developed for C. cervicornis. It is under-developed C. verticillata.
