I have several books, basket, knife, gloves no memory for names! But, I do know that of all the "maybe edible" fungi I manage to find I only identify about 30% positively. My family let me eat them and if I am not ill and still alive the next day they tuck in. In France you take your haul to the chemist and they ID them for you. The two main books I use are "Mushrooms and other fungi of Great Britain & Europe", Roger Phillips, Pan Books,ISBN 0 330 26441 9, which has lots of illustrations and "The Mushroom identifier", David Peglar & Brian Spooner, Apple Press, ISBN 1 85076 361 5, that has an edibility guide, ie some are not poisonous but taste naff or are to tough to eat. Can't help with US fungi though! Also I don't pick anything unless I am sure which some times means lying down to look under the fungi! I once sniffed a Fungi which I am sure resulted in an infection that lead to pneumonia!
