I have about 12 books in both languages on mushrooms Anno- last one bought is Carluccios. I like to cross reference from several sources if I am not 100% sure, and all my neighbours are experts so I am safe. Remember the 'Food for Free book' - still got my copy. Also got some of my dad's and grandad's old books (in French)- with drawings instead of photos.
I used to find those large puffballs in Leicestershire a lot- reminded me of the Tintin book- but never ever managed to make any of them taste good- tried, butter, garlic, parsley, curry even! Always ended up in the bin, I have to say.
