I got this book when I started getting interested in mushrooms. My first reaction was a total disappointment - I expected to be able to recognize at least half of the mushrooms in the forest, but barely managed to recognize 1 in 20.
After spending more time in the forest I realise that in a book this size it's impossible to have enough species. I got a book specific for Ireland, where I'm from, and even with this book it's difficult to recognize many species.
This book is a nice intro to the subject, but will not make you an expert.
In my original review I gave it one star. I think it deserves 2.5
