Information on Wild Mushrooms

The Pennsylvania State University has no current publication available on wild mushrooms. Several former University publications on the subject are now out of print.
There are a number of very poisonous mushrooms native to Pennsylvania and the United States in general and quite a few which may cause minor illness so we recommend that you consume wild species only after you are certain of their identity.
One must become familiar with the distinguishing characteristics of mushrooms in order to be competent to differentiate between edible and poisonous species. There is no "rule of thumb" or simple practice by which this distinction can be made.
The following illustrated publications may assist you in learning how to identify wild mushrooms so that you may collect them with confidence and enjoy their delicate flavors.
