I'm going NO. Oysters grow on dead trees almost always. They do NOT cup upwards like this. They may be edible (I wouldn't eat them), but they are not tan/white oysters in my opinion (and I've collected and eaten a LOT of white/tan and golden oysters).
Oysters do cup upwards, but only when they are about sporulate and not quite as drastic as the ones in this picture. It's about the only way to tell that they are ready to harvest before they make a mess of your grow area.
