This book is really good - not only covered with a good washable plastic cover for outdoor use, but full of lovely drawings in colour. Much better than photos, as the illustrator can show exactly what you need to look for. Alongside the edible muchrooms, the dangerous ones that look similar are given, and ways to discriminate them. The instructions are so good that as a rank beginner you can confidently identify something you find in a field or woods or even in your garden. The spore patterns are well detailed, and you can follow them easily. There are also recipes for the edible mushrooms. For the poisonous mushrooms symptoms are described, how they affect people.
All in all, this is a wonderful book.
