There’s a lot of information out there on magic mushrooms.

One question that often comes up is whether they expire or not.

Do magic mushrooms go bad over time? Are there any indicators that will let you know when they’re no longer safe to consume?

In this post, we’ll explore the answers to those questions and more.

How Long Do Mushrooms Last?

Fresh mushrooms are best for about 7-10 days, but can be stored in Tupperware or mason jars and kept at room temperature if you don’t plan on using them all that quickly.

Drying out the fresh ones using a dehydrator can increase their shelf life drastically.

Just make sure not to expose them directly sunlight because this could negatively affect their potency.

You can usually get magic mushrooms to last for about two weeks if they are stored properly.

How Long Will Dry Mushrooms Last?

Dried mushrooms need to be stored in a cool and dark place for their best shelf life.

They will last up to one year if kept at room temperature; six months if you keep them on the countertop with no air circulation or light exposure.

How To Store Magic Mushrooms

Once your magic mushrooms are dried, they should be cooled before handling.

When at room temperature, it’s time to transfer them into storage containers.

We recommend filling clean jars with tightly fitting covers and labels for each type of mushroom variety stored in order that you can tell what is inside without opening up the jar.

Keep these jars away from direct light, if possible, and store in a cool, dry place.

How Can You Tell If Mushrooms Have Gone Bad?

You can usually tell if your mushrooms have gone bad if they develop a sticky or slimy surface and get darker in color.

Once this starts, it quickly destroys the mushrooms. So, once you begin to feel slime on any one of them cook quickly for another few days.

What happens if you eat old mushrooms?

Many people are unaware that mushrooms can contain harmful microbes.

Eating a spoiled or rotten mushroom may cause gastrointestinal illness and even poisoning.

It’s not the actual fungus that will make you sick, rather the microbes that colonize the mushroom.
