Firstly I must give credit to all the mycologists who have made this book possible. Dr Derek Reid looked at a very great number of my specimens and verified the identifications; Ronnie Rayner oversaw the earlier work on Russula and Lactarius. For the new volume I have had an enormous input from Geoffrey Kibby, and I am greatly indebted to Alick Henrici for for his detailed work on the current taxonomy of the Basidiomycetes and Dr Brian Spooner of Kew for his work determining and updating the Ascomycetes.
To collect the fungi needed for the 1,200 photographs in this book, I calculate that more than 35,000 actual specimens have passed through my hands over the last 30 years. This has only been possible through the help enthusiastically given to me by mycologists in the field. Firstly, I would like to thank Ted Green, who has given up so much of his time, energy and skill to the project. Geoff and Jenny Stone, Malcolm Storey, Audrey Thomas, Irene Palmer, and Joyce Pitt also must have a special mention, and Nicky Foy for her continued support and tireless help in the field during all my travels.
