Generally, cooked mushrooms should keep for a good ten days in the refrigerator, though they might not last that long if they are fairly old when you prepare them. You can usually keep raw mushrooms for around ten days in your refrigerator, while cooked mushrooms will keep about as long. In your refrigerator, canned mushrooms will keep an extra three to four days once you have opened them. If you have any leftover canned mushrooms you do not intend on using in a couple of days, you can freeze them as well, which will keep them an additional 1 to 2 months.
You may decide to store or freeze your mushrooms, but keep in mind that when you store them in the refrigerator, the cooking time of cooked mushrooms is significantly shorter than the storage time of frozen mushrooms — 3-5 days, as opposed to 10-12 months. Sliced or unsliced, mushrooms may last 10-12 months in the freezer, although you are generally advised to freeze mushrooms when they are cut and cooked. If you are planning on keeping mushrooms (whole or sliced) longer than one week, they are best frozen.
You can only reach the above listed shelf life when you properly store mushrooms, whole, sliced, cooked, or dried. If you think that you are not going to be able to use all your mushrooms in one week, you may want to extend their life by freezing, dehydrating, canning, or pickling. If you notice mushrooms shrivel up too much, you are better off not using mushrooms in your recipes.

The best you can do is to monitor your mushrooms for as long as you can keep them in the refrigerator. If you are buying mushrooms close to theiruse-by dates, you are likely to find that they will last just a couple of days in the fridge. If you keep them in the refrigerator, you can expect that your cut mushrooms will not last as long as the whole mushrooms do.
Freshly picked mushrooms will last about 10 days when kept in the fridge. On the other hand, if you are cooking them (however), mushrooms will last at most 5 days. Most mushrooms only last for about one day at room temperature before starting to turn brown and turn slimy. On particularly warm, humid days, mushrooms may stay fresh for only about 12 hours at room temperature.
Keep in mind, the temperature and humidity levels may affect the length of time mushrooms stay at room temperature. Room temperature is not a great way to store fresh mushrooms, as these temperatures make them susceptible to developing bacteria.

If you have accidentally left mushrooms room temperature for longer than two hours, you are better off throwing them out. The shelf life of canned mushrooms dramatically decreases once they are opened, and even just a few hours of sitting at room temperature may make them unsafe to eat. If you put mushrooms into the refrigerator once they are cooled, they should keep very well, especially if stored sealed.
You can store dried mushrooms in an unwarm place, far away from light and humidity, or you can put them in the freezer. Keeping fresh mushrooms in a paper bag or poking some holes in a plastic container will keep them from getting too wet, and will help them to last a little longer. You can move the raw mushrooms into the bag once they are completely frozen, and that should keep them from sticking together into clumps. You can either defrost them in the refrigerator overnight, or just throw frozen mushrooms in anything you are cooking, let them defrost, then bake.
You can freeze mushrooms either cooked or raw, but freezing raw is a little trickier due to their higher water content. The reasoning for doing this is because when you bake the frozen mushrooms, the mushrooms outer pores quickly seal up with the heat, thus keeping them from becoming soggy or limp.
If you wish to keep them for a longer period of time, you can put them into a sealed plastic bag and store in your freezer. Another way to keep mushrooms relatively fresh is to store them in plastic bags lined with paper towels, which helps trap the moisture. If you are going to do this, be sure to freeze your mushrooms on parchment paper, and then transfer them to a sealed airtight bag quickly, pushing as much of the air out as you can. If you are going to store cooked mushrooms long-term, as with fresh mushrooms, you are best off freezing them in covered, airtight containers or plastic freezer bags. Like most vegetables, mushrooms will spoil and develop bacteria if they are stored for too long, so, yes, mushrooms will spoil.
Dried mushrooms can last a long time at room temperature, provided that they are stored correctly, either in a sealed airtight container or in a sealed bag, in a dark, non-soggy area. Sometimes, whole mushrooms stored refrigerated may begin to spoil in 4 days, depending on how long they were sitting with a supplier or at the store. It is best practice to keep cooked mushrooms on one of the shelves in your fridge, not on the doors, because the doors of your refrigerator experience many temperature fluctuations, which may affect the quality of the cooked mushrooms.

It is not recommended to freeze cooked button mushrooms because the quality would drastically decrease. If you know that you are going to be using up a lot of slices of fresh mushrooms soon, then refrigerating slices following the specified rules is fine, however.
Just like their non-stuffed siblings, cooked, packed mushrooms will keep in the fridge three to five days — stuffing, sadly, does not prolong their shelf life. Believe it or not, mushrooms last a good while: properly stored in a refrigerator, cooked mushrooms last for about four days. Cooked mushrooms can last around 7-10 days if stored correctly in a refrigerator at or below 40 degrees F. in a sealed container or a plastic zip-lock bag, but it is recommended that you consume your cooked mushrooms within 2 days in order to enjoy the best flavor and quality. If you are lucky enough and can find fresh mushrooms as far away from 40 degrees F. as you can get, you can also get away with using them a few days past the 2-week mark, but this is rare when shopping in a supermarket like most of us.
Can you eat mushrooms that have been in the fridge for a week?
Most chefs and experts agree that you can store raw mushrooms in refrigerator for up to two weeks before spoiling. Some mushroom species will last longer while others will try to spoil sooner. Other factors like fridge temperature and moisture levels can also affect the freshness of mushrooms.
How long can cooked mushrooms sit out?
Mushrooms are a type of fungi, and like all fungi, they can spoil quickly. When cooked mushrooms are left out at room temperature, they provide the perfect conditions for bacteria to grow. This can cause food poisoning, so it’s best to err on the side of caution and not eat cooked mushrooms that have been sitting out for more than two hours. sit out?
How to tell if cooked mushrooms are bad?
If you want to locate bad mushrooms then you can easily differentiate between good cooked and bad cooked mushrooms. Cooked mushrooms are still good if they are firm, have their original color, and smell earthy. Bad cooked mushrooms will be limp, discolored, and have a sour smell. If you’re unsure, it’s best to throw them out.
