Most inedibles aren't poisonous just aren't food, no nourishment and/or impossible to eat.
Some poisonous one needs to eat a lot to kill, in this area just a couple which a real threat.
I dunno, identifying them doesn't seem too hard if one sticks to a couple of edibles, just should know the resembling poisonous' and what's the difference. For example as Rusbernd told above >>/38836/ , he sticks with Boletes. I've no problem with Agarics because hereabout they have some great species (Macrolepiota procera for the win), just keep an eye on Amanita pantherina and the phalloides (especially on this).
In the woods most of the time I don't see at all or just very few. Sometimes a lot but most they don't resemble anything I would recognize. Maybe I should take photos and identify them systematically.
