I'm not an expert, but I think more info would be helpful. What type of mushroom is it? Did you purchase it, or make the spawn yourself?
If it's wine cap or blue oysters it's probably fine, they're known for being very hardy. You could also try adding some to a small bucket of substrate and checking on it in 1-2 weeks to see if the mycelium is developing.
