There are also a few things I have found in the past but have not eaten, for one reason or another. Things I know I can find and would consider trying are: Suillus cavipes (hollow-foot - local old-timers say they're good), Russula xerampelina (shrimp russula), Lactarius deliciosus, Chlorophyllum rachodes (shaggy parasol - formerly Lepiota rachodes) and some Agaricus species. I can reliably ID these.
I am also mildly curious about detoxifying Amanita muscaria, as has been discussed here. They are such nice, big, beautiful mushrooms and are fairly common. I guess I need to convince myself that it's safe.
