The French are mad about mushrooms. Every pharmacist has studied mycology, so that you can take any questionable mushrooms to the local drugstore for an expert opinion.
I remember an August Sunday that I spent with a French family at their country house in the Dordogne. After lunch (on a stone table under a hazelnut tree where we ate nuts from the previous year) we went mushroom gathering in the afternoon. That night's supper was an omlette made from the just gathered mushrooms. Unforgetable.
