For mushroom foraging I concur with Mike. I have a mycologist friend that teaches a field class at the local community college, I took his class and that gave me a good foundation. For books I like All that the Rain Promises and More because it's small and very thorough, but it's for the Western US so that might not be helpful for you. David Arora's Mushrooms Demystified is very good but it's too cumbersome to take on a hike.
