Book recommendations
Identification books for mushrooms should show a certain range of species.
A good description of the common edible mushrooms and their poisonous counterparts, i.e. poisonous species, 
with which edible mushrooms could easily be confused, are a must.
The many types of mushrooms described in the books listed below may initially be confusing to beginners.
However, if you have the appropriate forest experience, it is very helpful to have many comparison options.
Please note: Mushroom books do not replace experience in mushroom identification!
