There's at least one book on Minnesota's Safe Six, or such. Mushrooms that cannot be mistaken for anything dangerous. The puffball is one, and the morel is another. Hen of the Woods... um.... I forget the rest.

I went on some forays with the Minnesota Mycological Society and learned that I don't have the will to learn all there is to learn about mushrooms. Partly because I am a bad forager. I always look at the green plants and forget to notice anything brown.

K. [my HTML failed, but the book is by Stan Tekiela "Start Mushrooming the Foolproof Way"]
