Does he want the sclerotia or basidiomata? I get lots of material with sclerotia on damp fencing in my garden in Gloucestershire (see habitat photo) but maybe that is not what is wanted and is too far from Northamptonshire anyway.
I’ve just been out to check and the sclerotia are only just starting to form this year, and not on many infections yet. I’m expecting there to be huge quantities of them by February.
