I found this book seriously disappointing. Its layout and written information on edible and inedible/poisonous mushrooms is fine but the colour cast evident in most of the photograph illustrations is alarming. In very few was the grass a grass green. This may seem a trivial point but the failure spreads to all colouration in the image and this is supposed to be a book for the identification of what is safe and what is not in the world of fungi. It may be that the edition I own (2010) is particular but I would not trust any publisher who allowed such poor colour to go to press. If you do one thing right it has to be that.
The books I love, both as a designer and as a mushroom fan, are "The Mushroom Book" by Thomas Laessoe, and Roger Phillips "Mushrooms."
The first is beautiful - full of clear, accurate images (they seem to be photos with the background whited out and a little drop shadow added) with excellent colour. Its a gem but out of print and pricey secondhand. The good news is that it seems to have resurfaced as a smaller format paperback from the same publisher, Dorling Kindersley. The illustrations I have seen appear the same as in the original and, although at smaller size, they will be trustworthy. The hardback that I own you would steal from a dentist's waiting room.
Roger Phillips attractive volume offers amazing detail on over 1250 fungi. This may be too much for many but I remain amazed that this book provides so much, in well-ordered layout and scientific detail, for a little over £10. If you just need to trust a book for ID then ignore all the stuff about spore, amyloid reaction and tomentum, leave that to the nerds and simply enjoy owning something so comprehensive and good looking. You would steal this from a library.
I regret that my copy of this book will go to a charity shop, with a comment on the flyleaf about its quality. Because my brief five years in pursuit of fungi have taught me that there is no one picture that can show you the whole life of one mushroom I agree with another reviewer found in these reviews who says that the semi-serious fungi observer should be assisted by at least three different books. These will give three independent text/image summaries. For my third I am looking at the River Cottage Handbook.
