Welcome to the forum. I would recommend Roger Philips's Wild Food as a home reference book & Richard Mabey's Food For Free as a field guide to get you started.
Roger Philips's Wild Flowers, Trees & Mushrooms are also good home reference guides. I like the Blacks field guides & pair them up with Mabey's book when I go out.
Before you eat anything always cross reference and take care as some plants & mushrooms are extremely poisonous and difficult to identify. Happy foraging.
