Hilarious, unless you want to hunt mushrooms
You know those programs that translate from English to a foreign language and back again, to see what amusing nonsense you get back? That is the only explanation I can think of for the text of this book.
Also the photos are black and white and of mediocre quality; the same mushroom is repeated in different sections several times; there are blatant typos; some information is misleading or untrue. The saving grace was that it is SO bad no one could possibly take it seriously, otherwise it would be flat out dangerous.
I already have a couple good field guides and good books on general mycology, so it didn't hurt too much that this one was useless. I decided to enjoy it as an absurdity. DO NOT attempt to use this book to learn about mushrooms.
