I am a leading expert on edible/toxic wild (European) fungi. Ask me anything.
I teach people to forage for a living, and I'm the author of the most comprehensive book on (temperate European) fungi foraging ever published. (https://www.amazon.co.uk/Edible-Mushrooms-Foragers-Britain-Europe/dp/0857843974).
Ask me anything about European wild mushrooms (or mushrooms in general, I know a bit about North American species too). :-)
