Aparently 见手青 is mildly toxic yet commonly consumed in Yunan.
From what I read Suillellus luridus (见手青) is completely fine when cooked
Living toxins are much worse than nonliving ones because the living toxins can reproduce to dangerous levels even if you consume a tiny dose.
But if for some reason you think they're not dangerous, foods that contain nonliving toxins when unprocessed are also commonly eaten; a major example would be cassava. See also acorns, nardoo, fugu, and the Greenland shark.
Most things prefer not to be eaten; you can't let that stop you.
