Just discovered that I have two copies of the National Audubon Society Field Guide to North American Mushrooms. I would love to trade it for the field guide on shrubs. I'm not sure what the title is exactly, but I'd like to be able to identify things that are smaller than trees, but larger than wildflowers (which are the other two field guides I've got.) For the mid-Atlantic region, if there's more than one.
