Studies of truffles in Britain extend back for nearly 150 years, but the first monograph appeared only in 1954. This stimulated further collecting, which has led to the appearance of this latest account. Species with underground fruit-bodies are found in all the major fungal groups, and each group has been dealt with by a specialist. All species know are described and illustrated by line drawings and half-tone SEM images. Most species are illustrated by Lorna Minton.
