I've always wanted to learn mushrooms. I can't stand them if I know they are there, but if my wife slips them into a pizza or burger mix and doesn't tell me they usually slip by. Especially small pieces. It's a texture thing for me. But I've still always found it fascinating.
This place in York offers foraging and primitive skills classes. I am sure they would include fungus, but I don't know how much. I have never been able to make the schedule work.

I have not found anyone else offering similar classes and I certainly don't want to kill my wife. At least not all the time
