My Great Uncle & Aunt would collect mushroom and bring a bag back for my Grandmother. She would put them aside. The next day she would call them up and ask, "How are you feeling today?" If they were okay, she would eat the mushrooms.
To my knowledge they never had any trouble during everal decades of collcting.
BTW, a great identification book for the Northeast is George Baron's
Mushrooms of Northeast North America: Midwest to New England. Beautiful book that's well orgaized for easy idenfication and is loaded with wonderful photos that mak basic identification easy, although I would not recomnd using it as way to entify whether or not a species is edible. I, like others here, caution against samply shrooms unless one has been trained properly. He also has a website,
http://www.uoguelph.ca/~gbarron/index.htm. Another interesting website is
Tom Volk's Fungi.
BTW, the link to George Barron's book takes you to my Amazon affiliates page. I get a small portion of any sale as store credit. But I'm not offering the link as a way to promote myself (I have yet to sell any product because I don't promote it!), but rather to point out the links in the upper right corner under Browse By Category. This will open pages that list various nature books and field guides I have read and would recommend to fiends and Scouts. In fact, all of the books are in a large tool chest library that I haul to Scout outings to teach for advancement and merit badges. I would welcome any recommendations on other books that could be added to my "library."
