Button mushrooms should be refrigerated at around 4 °C
When storing mushrooms, it is important to let them breathe. Storing them in an airtight container or plastic bag will cause condensation and speed up spoilage. Instead, wrap them in paper towels or place them in a paper bag, which will absorb excess moisture, and then put them in the fridge. It is best to avoid putting them in the crisper drawer, as this is too moist.
If you have a large number of mushrooms, it is a good idea to set some aside for eating right away and others for later. Cooked mushrooms can be stored in the fridge for up to 10 days in a shallow airtight container or resealable plastic bag. If you want to keep them for longer, it is best to freeze them, but they should be cooked first. Mushrooms can be kept frozen for 6-8 months.
To ensure your mushrooms are fresh, look for those that appear damp but not wet or slimy. Touch them to check for moisture, especially if buying in bulk or at a farmer's market.

However, if you are planning to use your mushrooms within a few days of buying them, it is safe to keep them at room temperature for 1-3 days.

So, if you want to keep them for several days, it is best to place them in the fridge.
If you buy loose mushrooms, the best way to keep them fresh for as long as possible is to store them in a paper bag. As mushrooms age, they may begin to release water; the paper bag will absorb that moisture, keeping the mushroom’s surface slime-free for longer than if they were kept in an airtight container.
If you have a large number of mushrooms and want to keep them for longer than a week, it is best to freeze them. Mushrooms need to be cooked before they are frozen to preserve their quality.
