It's been eaten by the mycelia..., but this doesn't mean it's gone.What I mean is that it's likely that they'll fruit just fine, but the problem is that it's possible for the contam that was previously there to have produced something bad. There is no telling what sort of contam you had. Could have been the form of aspergillis that produces vitamin C for all I know. But it could have been a contam that produced either a carcinogen, or something far more deadly. While this is unlikely, it's a possibility, and I would throw them away.
But I've heard of many on the BB who didn't and they lived. Others didn't and some got the poops or whatever.
