It’s hard to tell from photos, but given they’re guaranteed to be saprotrophic (breaking down wood) and look to have decurrent gills + a certain size + grey/brown caps, i can’t think of anything they could be other than oysters (UK-based)
oysters are definitely one of the more common mushrooms to find in water damaged buildings. though they might absorb all kinds of poisonous compounds from the buildings they grow in so needless to say best to not eat them.

Absolutely true. Even in the wild some edible fungi can be toxic on the wrong soil/substrate e.g. amethyst deceivers are bioaccumulators of arsenic
