Told to me by a friend with long experience. There are old mushroom hunters, and there are bold mushroom hunters - but there are no old, bold mushroom hunters.
I pick mushroom with caveats. I know about five that I eat, and even then I am careful I know several of the poisonous mushrooms. Most mushrooms encountered, I cannot identify. Generally I am referring to the individual mushrooms in insufficient quantities to bother with even if edible. Usually I try to get a rough identification using Barron's field Guide. Anybody picking mushrooms for ingesting, without some knowledge probably has a screw loose.
Applies to plants as well, e.g.: http://www.ctv.ca/servlet/ArticleNews/story/CTVNews/1091824320067_87233520/?hub=Entertainment
Having just recently consumed the Non-ringed Honey Mushroom...with very uncomfortable digestive results....I can relate to this article. I have eaten this mushroom last year with no bad results, but this year? Not the same luck. No chance I mistook it for something else....but....no doubt it left me with a very uncomfortable 24 hours after digestion.
As far as I know, I never pick up mushrooms in wild becasue I can not determine them completely and it is dangerous. If your needs mushroom you can purchase on the stores and malls where they are controlled and conserved. I like mushroom a lot and I gro them in the garden but just for fun and researches, not for eating. I feel so sorry for those who got poisoned and in my counbtry I know many cases who accidentally got poison from mushrooms and passed way.
