Psilocybe Caerulescens


Identification & Description

P. caerulescens is a small, non-descript, brownish mushroom, just as most magic mushrooms are. Identifying these species in the wild is difficult, as they not only closely resemble each other, but also several non-psychoactive species, some of them dangerously poisonous. P. caerulescens adds to the confusion by being highly variable in shape and size.

This mushroom is reddish and sticky when moist but dries to more of a yellowish color. If cut or bruised, it will turn blue to blue-black, especially in younger specimens. While the mushrooms are usually small, they can occasionally be quite large.

Trip Effects

It’s difficult to find information on what taking P. caerulescens is like, although since this mushroom is biochemically very similar to P. cubensis, the character and quality of their highs are likely also quite similar. In general, psilocybin mushrooms usually bring euphoria, relaxation, feelings of connection, important personal insights, sensory intensification and distortion, and also some nausea—although since psilocybin tends to exaggerate whatever mental state the user is already in, debilitating anxiety is also possible. And while dangerous side effects are rare, they are possible. It’s important to follow certain basic safety practices for best results with any psychoactive mushroom.

Potency and Dosage

P. caerulescens is relatively low in terms of potency, but all that means is you have to eat more to get the same effect. Some people do suggest that low-potency mushrooms are better for beginners or for microdosing.

It’s always best to err on the side of too little rather than too much, since higher doses make bad reactions more likely.

Growing Psilocybe caerulescens

Although P. caerulescens is said to be easy to cultivate, and PF Tek will work, so it seems likely at least some other P. cubensis teks will work, too. But details are hard to come by. Colonization time is not clear.

Buying vs. Growing Psilocybe caerulescens

People who want to try eating P. caerulescens have two main options, buying and growing. In some areas, it’s possible to harvest this species in the wild, but foraging for magic mushrooms should only be done by experts, because of the danger of mistakenly harvesting a dangerous look-alike. Whether buying is better than growing (or the other way around) depends on the user’s situation—including their legal situation, since in most jurisdictions, possession or use of psilocybin in any form is illegal, and penalties can be draconian.

Growing mushrooms is always cheaper on a dose-by-dose basis than buying, plus it’s a way to get a reliable supply of a species that isn’t quite as popular as some of its relatives. Growing mushrooms is a fascinating hobby that some people really enjoy. Unfortunately, if your hobby comes to the attention of police, you may find yourself charged with manufacturing an illegal drug, among other problems. And since you’ll end up having mushrooms in some stage of growth in your house for weeks or months on end, security can become a real problem.

Buying mushrooms is a more attractive option if you really only want a dose or two at a time, or if you don’t want to bother with the work of cultivation.

In either case, we must be very clear; we can’t actually encourage you to break the law. We don’t want our readers going to prison.

While different strains of cubensis can also be found in the wild all over the world, the indoor-grown types are typically more potent. That’s one of the reasons that mushrooms you buy on the underground market are often stronger than the ones you pick in nature, since they’ve been bred for strength and are grown in specific substrates (the material in which you grow mushrooms) that increase potency.

However, you can find cubensis growing throughout the southern US, into Mexico, Central American, and South America. They also grow in Cuba, India, Southeast Asia, and Australia. In nature, they prefer to live on dung and can also be found on well-manured land in the spring, summer, and fall.

In mycologist Paul Stamets’ mushroom identification guide, Psilocybin Mushrooms of the World, he calls P. cubensis “the most majestic of the Psilocybes” because of their easy-to-recognize size and golden color. Like all Psilocybes, P. cubensis’ color depends on its level of hydration; they also turn a bluish color when handled due to psilocin oxidizing (basically being exposed to oxygen). Cubensis is distinct from other Psilocybe species because of its relatively large size and the way the mushroom’s cap widens with maturity. Overall, this is the most famous and widely consumed magic mushroom in existence, but it’s not the only one.
