Psilocybe azurescens: Natures Most Potent Psilocybin Mushroom

Psilocybe azurescens is commonly known as the “flying saucer” mushroom due to its unique UFO shaped cap. This potent mushroom is revered by psychedelic explorers for its strong psychoactive effects and sought by mushroom hunters for the thrill of finding it in its natural ocean-side habitat.

The root word “azur” in Latin-based languages conveys a deep blue color, which is mirrored in the species name Psilocybe azur-escens. Though this species was likely known to local communities, it was first formally documented in the Pacific Northwest in 1979. Later, in 1995, renowned mycologist Paul Stamets officially named the species after his son, Azureus, a name inspired by the striking blue bruising characteristic of the mushroom. This vivid blue bruising was a detail Stamets particularly valued, as mentioned in Michael Pollan’s bestselling book, How to Change Your Mind. ⁽¹⁶⁾

Visually, P. azurescens stands out from the Psilocybe crowd with its caramel-to-chestnut-brown cap, which features a distinctive central bump (known as umbonate). Taxonomically, It belongs to Psilocybe section Cyanescens, a collection of wood-loving mushrooms known for their intense psychoactive properties, distinctive blue bruising, and thriving in wood-rich environments. The habitat preference of Psilocybe azurescens sets it apart from other psilocybin-containing species, found along the West Coast of the United States, Psilocybe azurescens is particularly well-adapted to coastal dune ecosystems, often found growing on driftwood. Since its discovery, Psilocybe azurescens has been cultivated outdoors on patches of woodchips, enabling it to fruit away from its native Coastal Pacific Northwest range. ^(2, 3, 4)

What Are the Side-Effects of Psilocybe azurescens?

Psilocybe azurescens, like other members of the Cyanescens group, are associated with a physical impairment known as Wood-Lover’s Paralysis (WLP).

This temporary condition can lead to various symptoms, from muscle weakness and incoordination to a complete, short-term loss of motor control. Some individuals have also experienced a loss of motor function in the face and eyes.

WLP typically has a delayed onset, occurring about 4-6 hours after consumption of mushrooms. While most symptoms resolve within 24 hours, some cases may last longer. The exact cause of WLP remains unclear, and it is believed to be a rare occurrence.

Limited scientific literature on WLP currently exists, with most of the knowledge-base derived from anecdotal reports, personal experiences, or informal documentation rather than scientific studies. A summary report by the Oregon Health Authority reflects these findings, highlighting a lack of formal research on WLP. When considering consuming Psilocybe azurescens, be aware of this potential side effect and ensure you’re in a safe environment. ⁽⁶⁾

History & Cultural Significance of Psilocybe azurescens

Psilocybe azurescens may have first been discovered by a group of Boy Scouts camping along the Oregon coast near the mouth of the Columbia River around 1979, a story widely circulated in the mycological community. However, locating a well-documented primary source has proved difficult; so we include this tale as a piece of lore that should not be mistaken for fact.

Reports of this new, strongly bluing psilocybin-containing mushroom at some-time caught the attention of renowned mycologist Paul Stamets. Then, In 1995, Psilocybe azurescens was officially described to the scientific community by Stamets and his colleague Jochen Gartz in Integration: Journal for Mind Moving Plants and Culture. Stamets later highlighted this species in his book Psilocybin Mushrooms of the World, where he noted it as “one of the most potent psilocybin mushrooms,” sparking significant interest in its cultivation. ^(3, 8)

Interestingly, there is no evidence to suggest that Indigenous peoples of the Western United States utilized Psilocybe azurescens for any purposes. The absence of P. azurescens in the ethnobotanical records raises possibilities: perhaps these communities did not recognize its psychoactive properties or simply did not hold a significant place in their cultural and medicinal practices.

This lack of historical traditional use raises fascinating questions regarding the mushroom’s origins and relatively recent prominence in modern mycological and psychedelic circles. Some theories suggest that azurescens might have originated in regions like New Zealand and only later was introduced into its current habitats in the Western United States. This aligns with theories of its possible recent evolutionary development, ecological specificity, or inadvertent introduction through human activity. These factors contribute to its status as a notable species, primarily known only in contemporary contexts rather than through historical usage. ⁽¹⁵⁾

Psilocybe azurescens Genus, Species, Location, Strains and Cultivars

Azurescens is a species of fungi within the Psilocybe genus, known for its potent psychoactive properties. Unlike other psilocybin mushrooms, Psilocybe azurescens has no widely recognized cultivated or distributed strains. However, mushrooms found in specific locations are often referred to by the names of those regions, such as “Fort Stevens” or “Astoria,” indicating where they were originally discovered or commonly found.

Most spores or cultures available to the mycology community are typically labeled with the scientific name (Psilocybe azurescens) or nickname (flying saucers) rather than any specific strain name.

Where to Find Flying Saucers

• Psilocybe azurescens Mushroom Identification & Look-alikes.
  Psilocybe azurescens can be identified by studying it’s distinctive features and fruiting season. Key characteristics include habitat, a caramel- to brown-colored cap with a notably broad umbo (central bump), purple-brown spores, and strong blue bruising when the mushroom is handled or damaged. ⁽⁹⁾

  • The most common look-alike in regions where Psilocybe azurescens grows is Psilocybe cyanescens, another prized psilocybin-producing mushroom whose wavy cap edge can help to differentiate the two.
  • Other similar mushrooms with the same habitat include Galerina, Inocybe, and Stropharia species. Given that some of these look-alikes are toxic or potentially deadly, it is crucial to exercise extreme caution when collecting, identifying, and consuming Psilocybe azurescens to avoid the risk of poisoning or death. ⁽³⁾

How to Grow Psilocybe azurescens

Cultivation Basics

Cultivating Psilocybe azurescens outdoors is relatively straightforward and can be very rewarding when done correctly. One of the simplest methods involves gathering spawn or stem butts (cut stems after harvesting) from wild Psilocybe azurescens before transferring them to fresh wood chips in a suitable outdoor location. Alternatively, start with spores and use conventional mushroom cultivation techniques to grow the mycelium in a sterile environment before transferring the colonized substrate to wood chips in outdoor beds. Psilocybe azurescens is known for its aggressive growth and should rapidly colonize woody substrates. Maintaining a wet, partially shaded environment to support fruiting body development for optimal results.

Indoor cultivation is possible but presents more challenges, primarily due to maintaining the lower temperatures required for fruiting. Successful indoor growth typically involves growing the mycelium on wood chips before transferring it to a cool, moist chamber with sustained 45-55 °F temperatures. Mushroom cultivation processes for this species are well-documented on websites like shroomery.com, where growers share their experiences and tips for managing the unique requirements of Psilocybe azurescens. ^(10, 11) 

Substrate & Environment

The most suitable and easily accessible substrate for cultivating Psilocybe azurescens is woodchips. Alder (a type of birch) wood chips are generally considered the best option, although most hardwoods or conifer species will work. For optimal spawn production and expansion, it’s best to maintain temperatures around 65 °F, while fruiting requires cooler conditions, typically between 45-55 °F. Outdoor cultivation requires damp, disturbed areas with wood chips that receive partial or full shade. Landscaped city parks, habitat restoration sites, and similar environments are ideal for promoting the growth of Psilocybe azurescens. The best settings provide moisture and protection from direct sunlight, creating the appropriate conditions for successful cultivation. ^(10, 11) 

Harvesting, Drying and Storage

When gathering mushrooms from wild environments, keeping them clean is crucial to maintain freshness. Gently handpick each mushroom, trimming off the base of the stem to remove dirt and debris. Proper drying is vital to preserving the mushrooms for long-term use. To achieve consistent results, use a dehydrator on a low-temperature setting. Alternatively, place the mushrooms on a mesh screen in a well-ventilated area with a fan and dry until brittle. Protecting dried mushrooms from moisture is important to prevent spoilage. For long-term storage, keep them in a dry, sealed container, such as a mason jar with a lid, at room temperature (70 °F) in a dark place to maintain quality and potency over time. ⁽¹²⁾

Avoiding Mold & Contamination

When growing mushrooms outdoors, contamination is inevitable, but it generally doesn’t cause significant problems. The extended incubation period required for this species when grown indoors increases the probability of contamination, particularly with grain-based substrates. To reduce the risk of contamination, it’s advised to use a smaller amount of grain when colonizing woodchips, especially when compared to growing other Psilocybe species like Psilocybe cubensis. This approach helps maintain a cleaner environment during the colonization process.
