It’s staged in the sense that someone probably took the fan or face off and packed the insides of it with substrate and colonized grain. They then likely replaced the fan and covered the substrate either with a plastic bag or a tote of some kind to function as a humidity tent.
The mushrooms appear to have grown there. But it’s a novelty grow of cultivated mushrooms. Rather than mushroom spores landing there and somehow finding enough nutrients and the right conditions to fruit.
