What Are Magic Mushrooms?

Magic mushrooms are a category that can alter how you think and perceive the world because of their psychedelic properties. What makes these mushrooms so magical is because of the hallucinogen psilocybin. The chemical compound naturally occurs in over 150 mushroom strains scattered over subtropical parts of the world. Magic mushrooms got discovered by French Botanist Roger Heim in 1956 when the Wasson's brought them from Mexico. 

If you’re considering hunting magic mushrooms, you must know what characteristics differentiate them from other kinds. Firstly, these fungi have brownish or golden-colored caps with slender stems. Secondly, magic mushrooms bruise blue if you tear a small part of their cap or stem. 

Can Magic Mushrooms Go Bad?

Freshly harvested or picked magic mushrooms last only for a couple of days. They have a short shelf life because they contain moisture. The moisture makes shrooms go bad faster, so you won’t have an option other than throwing them if not used in a few days. Therefore, if you want to use magic mushrooms later, dry them first.

Three environmental factors are an enemy of both fresh and dried magic mushrooms. These include air, heat, and light. Exposure to any one of these agents will make magic mushrooms spoil faster. 

Can you eat magic mushrooms with mold? You should never eat magic mushrooms with mold on them as such mushrooms may cause allergic reactions in your body. What about expired mushrooms? When a magic mushroom reaches its expiry date, the chemical compound psilocybin decomposes. This decomposition of psilocybin reduces the efficacy of magic mushrooms. Moreover, expired magic mushrooms contain sufficient bacteria (harmful pathogens) on their surfaces. As a result, it's better to get rid of expired magic mushrooms rather consuming them.

How Can You Store Magic Mushrooms?

Psychedelic Mushroom Strains

As mentioned earlier, you should dry magic mushrooms first if you’re going to use them later. You can air-dry magic mushrooms or even use a dehydrator. On the contrary, if you’re going to finish using shrooms in a few days, skip drying them. 

When storing wet or dry magic mushrooms, you must protect them from three environmental agents, light, warmth, and air. Some techniques that you can use for storing these fungi include:

  • Using An Airtight Container

Store magic mushrooms in an airtight container like a glass jar or bottle to prevent exposure to oxygen. Otherwise, these fungi will decompose and lose potency faster. 

  • Keeping Shrooms In A Cool And Dark Environment

Magic mushrooms don’t like heat and sunlight. These two agents degrade the psilocybin inside the magic mushroom, causing the loss of its beneficial effects. Moreover, light and heat cause a mushroom to rot faster. 

To prevent magic mushrooms from rotting faster, keep the container of these mushrooms in a cool, dark place indoors, like an unreachable cupboard or drawer.  The best temperature range for storing mushrooms indoors is between 60℉ - 70℉.

When Should You Discard Magic Mushrooms?

  • Change In The Color Of Magic Mushroom

You shouldn’t use magic mushrooms that show a change in their natural color. Usually, these mushrooms have light-brown to golden-colored caps and often show blue discoloration because they contain psilocybin. However, if you notice any other stains on the mushroom’s body, they indicate bacteria or mold growth.  You shouldn’t consume such magic mushrooms and throw them away.

  • Mold Spots

If you notice a furry growth on a magic mushroom of a black, orange, green, or brown color, dispose of the magic mushroom. The woolly growth indicates mold growth, which you shouldn’t consume as it can cause various diseases.
