They look a bit young to say for certain, but there's certainly nothing that looks definitively un-Oyster to me.
I would say give it a day or two and check them again. My initial opinion was that yes, those do indeed look like very young fruiting bodies of Oyster mushrooms.
As to the dryness, I would check the ambient humidity. Are you keeping them in a closed container where they stay humid, or are they drying out between sprays?
