Did the ones you sprayed with bleach solution have a recurrence of the mold? Seems like the best bet would be to dunk the rest in a bleach solution, let them dry thoroughly and then store them in sawdust or vermiculite or sand or something along those lines. And if you have paper bags, I'd use them instead of plastic. But I'm hardly an expert. That just seems like a reasonable thing to do.
Hopefully, someone more knowledgeable than me will wander by.
