I've just been having a look through a few survival books and one thing that seems to come up again and again is the edibility test. If you're not familiar with this test, here it is ... http://www.survivaliq.com/survival/survival-use-of-plants_s1.htm#uet
However, I think that this test, especially in the way that it is portrayed in most books, is misleading and dangerous. This test isn't something you should do lightly. Basically, there are a few things out there that can kill you or make you seriously ill in very small doses. Don't use this test as a substitute to knowledge! This test is one designed to be used in times of extreme need (downed aircrew/military personnel behind enemy lines, etc) and not a way to find things that edible on a casual basis!
Also - don't try this one on fungi! It's doesn't work! Remember, you can physically eat pretty much every mushroom ... only some you only eat once!
This test is a test for when things become life-or-death, not a causal test to check if you've ID a plant correctly!
Just had to get that off my chest!
