For as far as i know, it is possible, BUT not recommended.
I ate several times some shrooms with mold on it, but what i did was: remove as much as mold as possible and after that, eat them.
I don't know if you will get any negative side-effects from it, but i can tell you that you stomach don't really like it.
If you make tea out of it, your stomach will 'cry' less :wink:
