This continues to be an outstanding autumn for toadstools in west Durham.
I'm pretty sure this beauty is the trooping funnel Clitocybe geotropa. Those gills remind me of cathedral roof vaulting.
There were about a dozen arrayed in a semi-circle around the roots of a hazel, on the riverbank downstream of Wolsingham in Weardale.
The largest specimen had a cap diameter of about 20cm.
A little further down the riverbank and this is alder bracket Inonotus radiatus, growing on a dying alder.
