Mycelium will not harm you. There is a fear of fungi unnecessarily spreading around and having one of these pieces will not cause you harm. The mycelium is left to dry and is in a dormant state so it will not fruit mushrooms. Even if it did, the only way it would hurt you is if you were specially allergic to this strain of oyster mushrooms.

Yes and No. During the last stage of drying it may fruit mushrooms, however, once completely dry it enters a dormant stage and needs to be soaked through for many hours to grow anything.
