While this book has nice photographs and good information, I think it worth pointing out the omission of the common mushroom 'psilocybe semilanceata' or liberty cap. For those who don't know, this is a magic mushroom and if picked is essentially a class A drug. I can only assume it's been deliberately left out on 'moral' grounds.
Why effectively censor a scientific book in this manner? Disappointing. Let's hope future editions treat their readers like adults.
