The Mystery Fatass magic mushroom is a rare and potent strain of Psilocybe cubensis, known for its chunky chode stems and golden caps.

Its origins are unknown, but it’s been on the market for several decades, though they’re notoriously difficult to source and come with a fat price tag. It’s not uncommon to see fatass shrooms retail for three times the price of Golden Teacher caps.

Some people believe the Fatass Strain was grown in the tropical regions of South America or may have also emerged as an isolation of common strains that produced these unique qualitative effects in its appearance.

The effects of the shrooms are intense, with auditory and visual enhancements without being overwhelming.

As far as growing Psilocybe cubensis mushrooms go, Mystery Fatass shrooms are considered one of the more challenging options. This strain often aborts mushrooms before they’re able to mature.

Still, the payoff is often worth the challenge for experienced growers looking to try something new. This strain has top-notch bag appeal.

Potency & Psilocybin Content

We couldn’t source an official lab test of the psilocybin content for the Fatass strain. One of the most trusted sources we typically reference is the Psilocybin Cup hosted by Oakland Hyphae, an organization committed to offering education and the safe use of entheogenic mushrooms.

Mushroom cultivators will submit a sample of their Psilocybe cubensis mushroom to compete for the highest potency, giving other growers or psychonauts an idea of what to expect from a particular strain.

However, to date, a sample of the Fatass strain has never been entered in the Psilocybin Cup.

On many Reddit and online shroom forms, anecdotal reports say this strain has more kick than your average cube shroom — and we tend to agree.

With that said, some mycologists debate the validity of a strain’s genetics in determining the potency of a mushroom. Many argue that while genetics may play a role in the potential for a mushroom’s psychoactive potential, the growing conditions are much more critical in determining the mushroom’s potency.

Where to Buy Mystery Fatass Spores

The Mystery Fatass strain is pretty rare — we’ve been unable to find it on most of the reputable vendors. We were able to score some to try them out from a local spore trading circle but have yet to find a solid vendor we can recommend.

Regardless, here are some of our favorite spore and grow kit vendors to checkout. You won’t find Mystery Fatass, but there are plenty of other great strains to try instead:

How to Grow Mystery Fatass Magic Mushrooms

Most Psilocybe cubensis mushroom strains grow similarly and aren’t known to be challenging to grow. Still, strict sterilization practices and ideal temperature and humidity are needed to have success.

If you’re looking to hit the ground running and grow your magic mushrooms the fastest way, you can purchase mushroom growing kits online, but if you’re willing to DIY a kit, you can save a bit of money.

First, you’ll need to acquire the spores, usually in a syringe, for ease of use. You’ll need this to innoculate your sterilized substrate mixture.

Before you dive into inoculation and handling your syringe, you must clean your work environment and tools. The Fatass strain isn’t known to be particularly resistant to contamination like other strains, so growing Mystery Fatass requires more careful attention to detail than your beginner cube shroom strains.

Once the fungi have successfully colonized your substrate, transfer the pods into the fruiting chamber and cultivate the best environment so your shrooms can thrive.

The ideal environment for most Cubensis strains, including Fatass, is as follows:

  • Humidity — High (>80%)
  • Temperature — 20–28 ºC (68–82ºF)
  • Light — None
  • Airflow — Low

The most exciting step of this process is the fruiting stage when you can start seeing your efforts come to life.

You should see pinheads emerge from your substrate cakes within a few days. While it might be tempting, please do not touch them and allow them to grow.

Fatass shrooms are known to grow in dense clusters and have chubby stems.

In most cube strains, you’d wait until the caps fully open, but that won’t happen with Mystery Fatass. The tops tend to remain closed overtop the fat stems. They’ll typically grow two to three inches tall and have a full golden cap when ready for harvest.

To harvest your magic garden, carefully pinch the mushrooms at the base of the stems. They should break off easily without effort. You can eat them fresh or fully dry before consuming them.

Once you’ve harvested your first flush, don’t toss out the cakes, you can expect three to four flushes of shrooms, with each one becoming sparser and sparser.

Similar Strains

While many different strains of Psilocybe cubensis are available, some are more potent than others. Three common strains known for their thick growth and high psilocybin content are A+, Enigma, and Koh Samui strains.

A+ Strain

The A+ strain of magic mushrooms is a well-known and popular strain that Mr. G, an infamous mushroom breeder, developed.

Like the Fatass strain, the A+ is known for its giant mushrooms and higher-than-average potency. These are a favorite among beginner and experienced cultivators alike as they’re relatively easy to grow, thanks to the strain’s inherent resistance to contamination.

A moderate dose can provide a memorable psychedelic trip with heavy visual hallucinations and spiritual experience.

Enigma Mushrooms

Enigma mushrooms are sure to impress if you’re looking for a unique mushroom.

Engima shrooms are still a cubensis strain but form thick, truffle-like shrooms with exceptionally high psilocybin and psilocin concentration.

Growing this strain requires more patience as it takes some time for the mushroom bodies to cluster and bloom, but the longer you let these shrooms grow, the more potent you can expect your harvest to be.

Golden Emperor

Golden Emperor is a genetic variation of the famous Golden Teacher strain created by Sporeslab.

This is a great strain to explore if you’ve enjoyed the experience of Golden Teacher shrooms but want something new. Golden Emperors has a slightly larger body than its predecessor while providing a gentle, euphoric, and insightful mushroom experience.

Koh Samui & Koh Samui Super Strain

Super Strain typically refers to an isolation of Koh Samui Mushrooms originating from Thailand.

Koh Samui Super Strain (KSSS) is known for its more bountiful flushes and higher resistance to contamination while still maintaining its characteristically high psilocybin potency for a high-energy, euphoric mushroom trip.

Both the Koh Samui and KSS strains are also known for producing mushrooms with the fatass growth pattern.

FAQs: Mystery Fatass Magic Mushrooms

1. Are Mystery Fatass Magic Mushrooms Safe to Consume?

Mystery Fatass shrooms are a strain of psychedelic psilocybin-containing mushrooms, which aren’t considered toxic in the way that they won’t cause damage to organs with long-term use. However, consuming any psychedelic substance does have its risks.

Taking large doses of magic mushrooms can trigger or worsen pre-existing mental health conditions. It can induce temporary anxiety, paranoia, and an increase in risky behavior, so approach any magic mushrooms, including Mystery Fatass, with a healthy degree of caution.

2. How Do Mystery Fatass Magic Mushrooms Affect the Brain?

Mystery Fatass shrooms contain psilocin and psilocybin. Psilocybin converts to psilocin, which acts on serotonin receptors in the brain. These receptors regulate mood, sleep, appetite, and much more.

When psilocybin binds to these receptors, it temporarily changes the normal functioning of these receptors, disrupting regular communication between brain regions and causing changes in perception, thought, and mood, as well as visual and auditory hallucinations. At least some of this effect is believed to result from psilocin’s ability to inhibit the default mode network (DMN).

The effects can vary from person to person and depend on the dose, but most people experience a greater sense of empathy and connectedness with nature. Sometimes high-potency shrooms like Mystery Fatass can feel overwhelming, causing feelings of anxiousness and paranoia, so it’s very important that beginners experiment under the proper conditions with smaller doses.

3. What’s the Dose For Mystery Fatass Magic Mushrooms?

The proper dosage of Mystery Fatass shrooms will depend on the type of experience you want. You should keep in mind that Mystery Fatass shrooms tend to have a higher-than-average psilocybin content (especially if you’re used to Golden Teacher shrooms).

For microdoses (a sub-perceptual dose) of Mystery Fatass, aim for 0.2–0.5 grams. This amount doesn’t produce a high, but it’s generally used to enhance creativity, productivity, and overall mood.

A standard dose for a euphoric psychedelic experience lies between 2-3 grams. At this dose, you can expect mild hallucinations, profound changes in thought, and intense emotional experiences.

4. What Are the Side Effects of Mystery Fatass Mushrooms?

Taking any magic mushroom comes with a certain degree of risk. The most common side effects of consuming shrooms include nausea, vomiting, fast heart rate, anxiety, confusion, paranoia, and frightening hallucinations.

The severity and duration of these effects can vary, and there’s no foolproof way to prevent them from happening. However, there are some steps you can take to minimize the risks,  like starting with a lower dose, being in a safe and comfortable environment with a trip sitter, and staying hydrated.

5. Are Mystery Fatass Magic Mushrooms Legal?

In the United States, psilocybin mushrooms, including the Mystery Fatass strain, are classified as a Schedule I substance, making it illegal to sell, possess and distribute under federal law. However, some states and cities have taken action to decriminalize psilocybin for medicinal and recreational use.

6. What’s the Best Way to Consume Mystery Fatass Magic Mushrooms?

Magic mushrooms can be consumed fresh or dried — but keep in mind the suggested doses for shrooms are typically dried weight.

Dried mushrooms are the most common way to consume them, but they can be hard on the stomach. Some people will brew the dried shrooms into a tea for gentler effects or mix them into food.

You can also take Mystery Fatass shrooms as capsules by grinding the dried mushrooms into a fine powder and measuring them into capsules for more controlled dosing and ease of use.

Other popular methods include the lemon tek method and psilocybin-infused honey.

Strains vs. Species: What’s the Difference?

The terms “strains” and “species” are often used interchangeably in the plant and fungi kingdom. However, there is a significant distinction between the two terms.

In general, a species can be defined as a group of organisms that can interbreed and produce offspring that are also capable of interbreeding due to their same genetic makeup. This definition is straightforward for animals but gets a bit more complicated when dealing with plants and fungi.

For fungi, species are often defined based on the type of habitat they inhabit or the way their spores are arranged. However, there is still some debate over how best to define species in the plant and fungi kingdoms, and further research is needed to reach a consensus.

The term “strain” is often used for plants and fungi commonly used by humans to describe a group that has diverged from one another over time (typically due to growing environments) but retains enough similarities to be classified as belonging to the same species.

For example, Psilocybe cubensis mushrooms are the most common species of entheogenic mushrooms, as they grow wild in many parts of the world and are easily cultivated. Still, hundreds of strains of cubensis shrooms within that species offer distinct characteristics.

Mystery Fatass magic mushrooms is an example of a cubensis shroom that offers a distinctive look for its unusually short and thick stems and golden mushroom cap that doesn’t fully open. It also has a higher psilocin and psilocybin content than the average cubensis mushroom, which warrants a new species grouping.

Identifying these different strains within a species commonly used by humans helps us to understand the type of ideal growing environments and expectations of effects for a given strain.
