Every species of Psilocybe has its own unique benefits and downsides. Despite that, many don’t know what species are the best for them. So, in this post we will talk about an uncommon species of mushrooms, Psilocybe cyanofibrillosa.

What Is Psilocybe Cyanofibrillosa?

Psilocybe cyanofibrillosa mushrooms are a little more potent and were said to have a more intense effect in users. These magic mushrooms can be found under many types of woods in different temperatures and humidity levels. They grow in Northern America, they are frequently found in British Columbia.

Psilocybe cyanofibrillosa, also known as rhododendron psilocybe, is a rare species from the Hymenogastraceae family. While it is also grown in other countries, these species have different chemical contents, and some can be deadly if consumed in large amounts. It’s essential to know which mushrooms you’re buying, even if you’re growing from spores.

How to Identify and Harvest the Cyanofibrillosa

The Psilocybe cyanofibrillosa is actually quite easy to identify because it has a very distinct shape. It often grows in clusters on dead hardwood trees or stumps, but it can also grow on living trees as well. The mushroom has a conical cap covered with brownish scales when wet (yellow or gray when dry), and underneath that cap there are gills that run down the stem; these gills are off-white at first but become brown (a bit of purple too) as they age.

The stem is white or brownish white and hollow throughout its length, and it is of medium length, depending on where the mushroom was growing when you found it.

How Do You Grow Psilocybin Mushrooms?

Psilocybe cyanofibrillosa grows best in rich soil that has been fertilized with manure or compost. The best time to plant the spores is from October through December, when temperatures are between 50 degrees F and 70 degrees F. 

Spores are best planted on soil or compost that has been sterilized for at least 24 hours before planting. You can also use a small amount of water from boiled potatoes as an alternative sterilization source if you don’t have access to electricity. Planting too many spores will result in poor growth because there won’t be enough nutrients available for each individual spore to grow into a mature shroom.


A microdose of psilocybin is a sub-perceptual dose that produces minor effects on the body and mind. The purpose is to gain insight into one’s own mental state, be it mental or spiritual. It can also be used to enhance creativity, though some artists have said that it doesn’t work for them.

Dosage can vary depending on how strong your mushrooms are, but as a general rule of thumb, start with 1g (0.03 oz). This is not an exact science, so start with a small dose and work your way up from there if you feel it’s necessary.

The effects will last between 3-4 hours, depending on the strength of your mushrooms and your metabolism rate, so don’t expect to get high for the whole day. There are no side effects other than nausea if taken in excess (over 0.07 oz), so make sure you take care not to consume too much!


Psilocybe cyanofibrillosa potency depends on how active they are before harvesting, the temperature at which they were stored etc., however they tend to be relatively potent compared to other psychedelic shrooms.
