My bucket mushrooms died (lack of humidity) - will they grow back or should I discard?

I was doing so so well... after a month they started pinning so I moved them to an outdoor place with hgh humidity that was pretty dark. Then I noticed flies and bugs and I freaked out so I brought them into the kitchen and they've all ceased to grow - all shriveled up, no growth fo 3 days now.
Should I leave them - will the mycelium continue to produce shrooms, (oysters), or is the mycelium dead and I need to start again?
I'm so peeved with myself. Managed to get one hella tasty meal out of them though
Thanks guys
