The best way to know if mushrooms are bad is to examine their appearance. Check for discoloration, dryness, sticky skin, and an earthy smell. If you notice any of these, they are probably not good for you. You should also avoid eating any mushrooms with slime or mold. For these symptoms, it’s best to use cooking oil instead. If you’re still unsure, check with your local health department.


One of the most common signs of spoiled mushrooms is discoloration, which is the most obvious symptom of rotting. Other red flags include brown spots and uniformly dark colors. If these are present, toss the mushrooms immediately. They may also be slimy and have a foul odor. The best way to prevent food poisoning from mushrooms is to toss them as soon as you notice them.

Brown spots and wrinkles are other signs of spoiled mushrooms. Mushrooms with these characteristics are likely rotten and have started to turn rancid. The covering on the mushrooms is slippery and is a dead giveaway that the mushroom is past its prime. In general, mushrooms should smell sweet when fresh. However, if the covering is discolored or crumbly, discard them. You can also use lemon juice to delay discoloration.


There are several ways to tell if your mushrooms are bad. First of all, you can look for wrinkles on them. While this does not necessarily mean they have gone bad, it is a sign that they are dehydrated. Another sign is if the mushroom is getting shriveled and has dark spots on it. As mushrooms contain 95% water, they tend to show signs of dehydration more clearly than other produce. To avoid this problem, you should rehydrate your mushrooms by adding them to a soup or stew.

You should also watch for any signs of mold or bacteria. While this may seem like a good thing, this doesn’t necessarily mean that the mushrooms are bad. Depending on the variety, mushrooms can start to decay within a couple of days. You can save mushrooms for up to three or four years if you store them properly. If you store them properly, dried mushrooms don’t spoil as quickly as fresh ones.

Sticky skin

You may be wondering if you should eat a mushroom that has a slimy skin. It is important to wash mushrooms properly before cooking them.

You may not want to cut the mushroom around the stains because the spots will only get worse. So, you should always keep an eye on the mushrooms you cook. And remember, these fungi are great sources of nutrients. So, you should try to eat them whenever you can.

Earthy smell

One of the most important signs of bad mushrooms is their smell. Bad mushrooms have an ammonia-like smell or fishy odor. A normal earthy odor will be more pleasant. When picking mushrooms, remember to look for discoloration, slimy coatings, or foul odors. If you find any of these signs, it’s probably time to throw them out.

If the mushroom has a pungent ammonia smell, it is likely spoiled. Some fungi even have fishy odor. Luckily, you can easily determine which mushrooms are bad by their smell and appearance.

Dark spots

The first sign of bad mushrooms is a brownish spot. This usually indicates that the mushroom is going bad, but you can also look for bruises or bruising.

When mushrooms are past their prime, they will begin to turn brown. This is caused by the formation of an enzyme called tyrosinase. This enzyme reacts with oxygen and causes the mushrooms to go brown. The mushroom will also begin to shrivel and wrinkle, and it will start to smell bad. These are all signs that the fungus is about to go bad. If you notice any of these symptoms, it’s time to discard the mushroom. Try using different storage methods to keep mushrooms fresh.
