The world holds many secrets. New species of various organisms, including fungi, are discovered and described practically every day. One of these is the mushroom Psilocybe azurescens, discovered and defined relatively recently, in the mid-1990s. For many mycologists, this was a breakthrough in the field, partly because it is—to date—arguably the most powerful of the “magic” mushrooms that grow in nature. For this and other reasons, I want to present this incredible member of the kingdom of fungi in this article. I encourage you to read it!
Psilocybe slender-headed mushroom – what is this mushroom?
The presented species is another member of the Psilocybe genus, which already reveals that it belongs to the group of organisms that produce psilocybin and psilocin. It’s worth noting that it is the most potent representative of these species. It has been reported that it can contain up to 1.8% of this alkaloid by dry weight (for comparison, the commonly known Psilocybe cubensis has a value of 0.63%, which is almost three times lower). And what does it look like? Find out below.
Description of the appearance of the slender-headed bald eagle
The cap typically has a diameter of between 3 and 10 centimeters. In the early stages of development, it is conical or convex, but as it matures, the edges become strongly raised to the sides, leaving a clearly defined wart. Hence one of the common names – flying saucers (another is “blue angel” due to the intense blue discoloration when damaged).
The texture of the “cap” is slender, but becomes sticky when exposed to moisture. It has beautiful colors – slightly orange/caramel shades with lighter edges. It is usually quite regular, but can become slightly wrinkled with age. The gills themselves are brown, and damaged ones darken.
The stem grows to about 9 to 20 cm. Its diameter is usually 3 to 6 mm. It is white, but with age (and at the base) it darkens towards brown. Like many other Psilocybes, it becomes hollow as it matures.
The mycelium is particularly intriguing. On one side, it forms tangles of hyphae, and on the other, it can have beautiful, azure shades. For this reason, it would also be an attractive material for microscopic examination.
Properties and Actions of Pseudomonas slendericus
As the most potent representative of its genus, it has the potential to induce powerful hallucinations. One gram of the dried herb is enough for the user to experience an altered state of consciousness with visionary states for 6 hours (assuming these are average values, without taking into account individual predispositions).
So how does it work? Much depends on the individual’s sensitivity. However, it has been suggested that under favorable conditions, the alkaloids contained in the presented mushroom can affect, among other things, the emotional state (by improving mood and elevating the spirit), induce euphoria, and even hallucinations. The presented mushroom has been reported to produce different visual effects both with open and closed eyes.
In what conditions does Psilocybe azurescens grow?
The natural habitat of this mushroom is quite small. It is indicated that it occurs naturally only in the northwestern part of North America, including Oregon, California, Washington State, and the west coast of Canada. Some data indicate that it adapts well to other habitats (there is information that this species was also found near Stuttgart, Germany), which indicates a high adaptability.
As a saprotroph, the slender-footed squirrel grows in forests and coastal dunes. It favors tree remnants (including bark-covered substrates) and other plant debris, among other habitats. It also prefers sandy substrates. It grows in tight clumps in shady locations, typically fruiting from late September to even early January.
This is one of those psilocybin mushrooms that—unlike, for example, Cuban Psilocybe—does not require a “tight” temperature range. Colonization occurs efficiently within a range of 16° to 24° Celsius. Fruiting, on the other hand, may require even lower temperatures, as low as around 7° C.
It should be noted that colonization itself is quite slow. In labs, the mycelium develops for up to 6 months before it begins to produce fruiting bodies.
The History of the Discovery of Psilocybe azurescens and Its Uses
Scouting in the United States, especially in the past, is very popular. Like our Boy Scouts, young people often venture into inaccessible and less hospitable wilderness areas. This particular group of Scouts has made a mark in the annals of mycology. They happened to be camping in the Columbia River Delta in Oregon. Did these boys know what they were dealing with? It’s hard to say, but by eating them, they experienced their first “high” thanks to Psilocybe azurescens. The fact that it wasn’t described at the time is likely because it was most likely confused with other species of the same genus, i.e., Psilocybe cyanescens and Psilocybe astoriensis.
When was the mushroom described?
Was this actually the first known encounter with this species? It’s hard to say, but that’s how the stories go. What we do know is that the mushroom itself was recognized and introduced to the world in 1995. It was discovered by two mycologists, Paul Stamets and Jochen Gartz, who classified it and defined its characteristics. It’s worth noting that the name, Psilocybe azurescens, comes from the genus and, on the other hand, from the name of Stamets’s son, Azureus. Since then, many licensed (and certainly “underground”) laboratories around the world have become interested in this species as one of the most effective producers of alkaloids.
Uses of Psilocybe azurescens
What do we know about whether these mushrooms were used in any rituals in the past? Practically nothing. However, we can assume that this was the case, mainly due to the fact that they induce “visions” and analogies with the use of other species of this genus. Mushrooms containing psilocybin – natural psychedelics – have been of interest to shamans and primitive cultures in general for centuries. They helped them contact the gods.
What we know for sure is that, like other Psilocybe organisms, Psilocybe slender-headed mushrooms can potentially be used therapeutically. That is, if the law allows them to be used for medical purposes. For now, however, the cultivation, possession, and use of psilocybin mushrooms, including the aforementioned ones, are prohibited. species, is illegal in most countries (although some states and cities have decriminalized possession for personal use).
Psilocybe azurescens – the mighty one among magic mushrooms
Organisms from this kingdom are revealing more and more secrets to us. Scientists are also increasingly interested in mushrooms. Some are used for so-called biohacking, i.e., enhancing certain positive traits. Others, such as the Psilocybe azurescens, can be an ally in the fight against depression, PTSD, bipolar disorder, and other mental ailments. For mycologists, on the other hand, they are amazing specimens worth studying. Although in this case we can only observe the mycelium life, Psilocybe azurescens can provide an incredible spectacle that any attentive observer will appreciate.
