There are only a few different psychedelic mushrooms that grow naturally in the Philippines, the most common and popular of which belongs to the genus and species Panaeolus cyanescens.
However, there are some less popular Psilocybe cubensis strains that have been collected from around the Philippines as well — the most prevalent of which is the Quezon strain.
The Quezon shroom strain is best known for producing large, dense mushrooms with chunky caps. Despite its allure, it’s still fairly challenging to get your hands on spores for this strain in the United States and Canada.
This is the ultimate guide to Quezon magic mushrooms. We’ll explain what little history is known about this strain, what the average potency you can expect is, and where you might be able to find some spores.
What Are Quezon Shrooms?
Quezon shrooms also referred to as the Philippines strain, are a strain of psilocybin-containing mushrooms. Like most other magic mushroom strains, the Quezon strain is classified as Psilocybe cubensis.
Little is known about the origin of this strain or who’s responsible for collecting and developing it into what it is today. It was reportedly collected in a garden in Quezon City sometime around 2010.
This strain is considered a prized mushroom strain by growers because the fruiting bodies can grow to massive sizes, yielding a large harvest and photograph-worth specimens.

Strains vs. Species: What’s The Difference?
The term “species” refers to a scientific classification of mushrooms that have identical genetics. Different species can look different and have different potencies and growing habits, and these differences are often attributed to the species’ genetics.
The term “strain” refers to genetic samples within a species that produce different traits or characteristics. The variances between strains can include anything from appearance (colors stem or cap sizes, etc.) to potency and chemical makeup.
The strain terminology is used to differentiate between genetic samples of plants that humans use for recreational and medicinal purposes as well. For example, the cannabis strains Northern Lights, Girl Scout Cookies, and Purple Haze all look different, grow differently, and have varying levels of THC and CBD, yet they all belong to the Cannabis sativa genus and species.
Quezon Shrooms Potency & Psilocybin Content
There are no specific data available for the potency of this strain, as is the case with many others, and there are no entries for this strain in the Oakland Hyphae Psilocybin Cup to confirm potency. We can only use trip reports of people who have taken Quezon shrooms to get an idea of how potent they are.
Most users report an average trip with mild visual hallucinations and a deep sense of connection to the world around them. Based on the experiences of users, we estimate that the potency of this mushroom is roughly average, which lands the estimated tryptamine content somewhere between 0.75% and 1% by dried weight.
Quezon Shroom Variations & Genetic Relatives
Given the overall lack of popularity of the Quezon strain, it should come as no surprise that there aren’t any popular variations that have been isolated thus far. However, there are plenty of strains that come from other regions of Southeast Asia.
An infamous amateur mycologist, John Allen (often referred to as Mushroom John), took a trip to Southeast Asia in the 90s, where he collected spore samples from all the Psilocybe cubensis mushrooms he could find. Many of the samples he gathered on this trip are still in circulation on the open market today. Some of his most prominent findings included Ban Hua Thanon, Burma, Chitwan, Thai, Koh Samui, and nearly a dozen others.
Where to Buy Quezon Shroom Spores
Unfortunately, Quezon shroom spores are typically difficult to come by. They circulate among enthusiasts and mycologists, but there are very few places to buy them commercially.
How to Grow Quezon Shrooms
If the idea of mammoth-sized mushrooms is interesting to you, the Quezon strain is definitely worth your time. The problem is that these large mushrooms are sometimes hard to get. You can get some large mushrooms pretty easily using the BRF tek method outlined in our beginner’s guide to growing magic mushrooms — but to really get the full potential of these giants, you’ll need to use rye grain or manure and a proper casing tray.
Give these zoomies plenty of water (but not saturated) and lots of clean airflow. Be patient with them and avoid harvesting as soon as the veil breaks. These suckers will continue to grow rapidly for a full day or more after the veil breaks.
Best Alternative Strains: Other Large Mushroom Producers
Since most users and cultivators will likely have some difficulty finding spores for this strain, some might want to try similar strains that are more readily available. We’ll offer some good Quezon alternatives below.
1. South American Shrooms
The South American strain hails from Venezuela and has a higher potency than the Quezon strain. However, like the Quezon shrooms, South Americans will grow to massive sizes and produce photo-worthy fruiting bodies. In fact, this strain holds the record for the largest Psilocybe cubensis strain ever grown.
2. Orissa India Shrooms
The Orissa India strain is another one that is well-known for producing large mushroom samples. This strain held the record for the largest cubensis strain until a South American took the record. This strain also has a higher potency than the Quezon strain.
3. Amazon Shrooms
The Amazon strain — also called the PESA strain or the Pacifica Exotica Spora Amazon strain — is another that produces massive fruiting bodies, making it a popular choice for cultivators. This strain has a higher potency than Quezons and tends to be a little easier to coax larger fruits from even under less than ideal conditions.
4. Paraguay Shrooms
Finally, Paraguay shrooms have a lot in common with the Amazon strain. Although the fruiting bodies are slightly smaller than those of the Amazon strain, they’re still larger than average. This strain can also be difficult to come by, but it’s more widely available than the Quezon strain.
Final Thoughts: Quezon (Philippines) Shrooms
The Quezon magic mushroom strain was originally collected in a garden in Quezon City in the Philippines. Although it’s not a terribly popular strain, it’s well-known throughout the magic mushroom cultivating community for its massive fruiting bodies that continue to grow even after maturity.
The Quezon strain has an average potency and tends to produce mild visual hallucinations when consumed. It’s believed to be related to several other strains of Psilocybe cubensis that grow naturally in Southeast Asia, although most others from the area have a higher potency.
