The pictures in this guide are incredible! The picture above pales in comparison to the actual book cover, and it is too bad that there has not been a picture of one of the pages included.
Each type of mushroom or fungus has its own half page section. The sections have a large and vivid pictures of the species. Did I mention that the pictures are incredible? Usually sections have supporting pictures such as top views and gill views of the mushrooms. It also gives species information, season availability, and dimensions in centimeters of the cap and the stem. The discussion in the section gives written information on description, occurrence, and similar species.
As far as edibility of mushrooms, this guide gives a symbol for the categories of edible, non-edible, and poisonous. This is really the only discussion of edibility, so this book is not a guide to eating mushrooms, but an overall guide to mushrooms.
The cover is close to being waterproof, which makes it excellent for taking into the field. The pages are high-quality paper. This book is a tremendous deal!
