50% inedible
By this I mean, either too tough to chew, like some woody shelf mushrooms, or just plain indigestible, like oak or maple leaves, for example.
25% " edible, but not incredible"
There are a lot of mushrooms out there that are edible, but tasteless.
20% will make you sick
In this category I put things that will irritate your digestive tract. In mild cases, this means that you will throw up after eating the mushrooms. In more severe cases, it means that your entire digestive tract becomes extremely upset and expels whatever is inside it, in whatever direction is quickest. In very severe cases, your digestive tract continues trying to expel whatever is in it for a few days.
