The mushrooms from the bolete family here in Germany often stain blue (or some other color) when bruised but most are very good mushrooms for eating. For example, Imleria badia, Neoboletus erythropus and Suillus grevillei. The last one is even slimy but you can just remove the cap. (There is also this really tasty gill-having mushroom Lactarius deliciosus that stains green). Also, Armillaria can do bioluminescence but are also edible! I agree with checking for fungi infections of mushrooms and to learn to ID the deadly poisonous Amanita species (funnily enough, there are some really good edible ones in the same genus!).

Your guide to carefully test foraged organisms is definitely helpful. However, when foraging mushrooms you have to keep in mind some additional things. Many, if not most mushrooms are really toxic when eaten raw! People frequently get poisoned while eating edible mushrooms that are not cooked enough. They apparently often contain hemolysins. Also, there are a few tasty mushrooms that can be toxic if eaten in combination with alcohol. If you go foraging mushrooms, better try to learn some groups, how to distinguish them and what are their characteristics than trying to test by your body’s reaction. But yeah, if you were to be without any food in the wild maybe it helps to know how to test for edibility.
