That's not how mushrooms work, stop freaking out.
Mushrooms don't "leach out" toxins on your hands or cross contaminate eachother (unless they VISIBLY exude a latex, like the Lactarius genus). Most edible mushrooms' mycelium is intertwined with deadly ones. Boletes grow in the same places as amanitas and even amanitas phalloides. They sometimes grow very close to eachother, it doesn't make them toxic by proximity. You can perfectly handle an amanita phalloides and even smell it (yes, you can smell all mushrooms, the all have a smell - mature death caps smell like withered roses).
In fact you can also take a bite to taste them, the only condition is to never ever swallow. Spit it out, rinse your mouth. Mushrooms are only dangerous when eaten and digested. Though I wouldn't recommend doing that.
>the most deadly in the world
By number of yearly deaths, other mushrooms contain amanitins and can cause irreversible organ damage, some contain other toxins and are just as deadly, or more.
Galerina marginata contains six times more amatoxins by weight than the death cap, Lepiota brunneoincarnata contains them too, Amanita virosa (called destroying angel because it's entirely white) which also contains phallotoxins on top of amatoxins.
There's some shroom in Asia that only needs a couple of grams to kill.
