How Long Does Lion’s Mane Last? Does it Go Bad?

Lion’s Mane mushroom, scientifically referred to as Hericium erinaceus, is an edible fungus known for its unique shape and nutritional benefits.

It has a long history of medicinal use in China and Japan and is widely recognized for its potential to aid in nerve repair and cognitive improvement.

But how long can this mushroom last, and can it go bad?

Lion’s Mane mushroom can last up to two weeks in the refrigerator when stored properly. However, it is recommended to consume it within a week for the best flavor and quality. Lion’s Mane can also be dried, stored in an airtight container, and kept for up to a year.

What is Lion’s Mane?

Lion’s Mane is an edible mushroom that typically grows on hardwood trees such as oak and maple trees. It has a unique appearance, resembling white pom-poms or a lion’s mane, hence its name.

The mushroom’s texture is delicate and chewy, with a mild seafood-like flavor that some compare to crab or lobster.

In addition to being a delicious culinary ingredient, Lion’s Mane has been used for centuries for its potential medicinal properties. It contains compounds like beta-glucans, erinacines, and hericenones, which have been shown to have antioxidant, anti-inflammatory, and neuroprotective effects.

How Long Does Fresh Lion’s Mane Last?

Fresh Lion’s Mane mushrooms are highly perishable and require proper storage to maintain their freshness. When kept in the refrigerator, Lion’s Mane mushrooms can last for up to two weeks.

It is essential to store the mushroom properly to ensure its longevity. First, make sure the mushroom is dry and free of any dirt or debris before placing it in a paper bag. Avoid using plastic bags as they can trap moisture and promote spoilage. Once inside the paper bag, place it in the refrigerator’s crisper drawer.

It is important to note that while Lion’s Mane may last up to two weeks, it is best to consume it within a week for optimal freshness and flavor.

How to Tell If Lion’s Mane Has Gone Bad?

While Lion’s Mane has a relatively short shelf life, it is still possible for it to spoil before the two-week mark. Here are a few signs to look out for to determine if your Lion’s Mane has gone bad:

Slimy or Mushy Texture

If you notice your Lion’s Mane has a slimy or mushy texture, it could be a sign of spoilage. This texture change occurs when the mushroom’s moisture content is too high, leading to bacterial growth and decay.

Foul Odor

A bad smell is another clear indicator that your Lion’s Mane has spoiled. If it smells sour or rotten, it is time to dispose of it immediately.


Lastly, if you notice any discoloration, such as dark spots or browning, it’s a sign that the mushroom is starting to go bad. A healthy Lion’s Mane should be white and uniform in color.

How to Store Lion’s Mane?

Lion’s Mane requires special storage to maintain its freshness and prevent spoilage. Here are a few tips for storing Lion’s Mane:

Paper Bag

Avoid using plastic bags when storing Lion’s Mane as they can trap moisture and promote bacterial growth. Instead, use a paper bag to allow for air circulation.

Crisper Drawer

Once in the bag, place the Lion’s Mane in the refrigerator’s crisper drawer. This drawer helps maintain a consistent temperature and humidity level, which is essential for preventing spoilage.

Keep Dry

Before storing, make sure the Lion’s Mane is dry and free of any dirt or debris. If it is wet, use a paper towel to gently pat it dry before placing it in the bag.

Airtight Container (For Dried Lion’s Mane)

If you have opted to dry your Lion’s Mane, store it in an airtight container to prevent moisture accumulation. Dried Lion’s Mane can last for up to a year when stored properly.

Can Lion’s Mane Go Bad?

Like all fresh produce, Lion’s Mane can go bad if not stored correctly. Its high moisture content makes it particularly susceptible to bacterial growth and spoilage. As mentioned earlier, you can tell if your Lion’s Mane has gone bad by looking for signs like a slimy texture, foul odor, and discoloration.


Lion’s Mane is a delicious and nutritious mushroom with potential medicinal benefits. When stored properly, Lion’s Mane can last for up to two weeks in the refrigerator. It is recommended to consume it within a week for optimal freshness and flavor. If you prefer to dry it, Lion’s Mane can be stored in an airtight container for up to a year.

To prevent spoilage, store Lion’s Mane in a paper bag in the refrigerator’s crisper drawer, keeping it dry and free of any dirt or debris. If stored correctly, it is possible to enjoy the mushroom’s unique seafood-like flavor and potential health benefits for an extended period.
