Moldy black truffles-are they edible?
From Google:


  While you probably won't die from eating fungus, keep in mind that foods that are moldy may also have invisible bacteria growing along with the mold. The colorful mold you see on the surface of food is just the tip of what is going on inside. Most molds are harmless, but some are dangerous. Some contain mycotoxins.


My suggestion is that unless you are trying to make penecillin, throw them away. The risk is not worth it. Italy is still there.
