Scientific Classification

The fascinating world of psilocybin mushrooms, specifically those within the genus Psilocybe, reveals a rich tapestry of biodiversity. Psilocybe aztecorum, a member of this intriguing group, resides under the family Hymenogastraceae. This classification places it among various hallucinogenic mushrooms, each with its unique psychoactive compounds that have intrigued both the scientific community and cultural practitioners for centuries. The genus Psilocybe is renowned for its wide array of species that produce psilocybin, a compound responsible for their psychoactive properties. These mushrooms typically fruit on decomposing woody debris, playing a vital role in their ecosystems by contributing to the decomposition process and nutrient cycling.

Historical Naming and Current Status

The journey of Psilocybe aztecorum from its initial discovery to its current scientific standing is a tale woven with the threads of exploration, cultural significance, and scientific inquiry. French mycologist Roger Heim first identified the species in the mid-20th century, guided by specimens collected in central Mexico. This initial classification highlighted its distinct characteristics and its sacred usage among indigenous populations, notably for spiritual and divinatory rituals.

Gastón Guzmán, a prominent figure in the study of Psilocybe mushrooms, later refined the taxonomy of P. aztecorum. He provided detailed descriptions that emphasized its unique features, such as the hygrophanous nature of its cap and the presence of conspicuous white rhizomorphs at the base of its stem. These morphological traits, along with spore color ranging from dark yellowish brown to dark violet flesh reddish brown,and the flesh’s reddish-brown hue upon application of potassium hydroxide, distinguish P. aztecorum from other species within the genus.

Guzmán’s contributions extended beyond mere classification; they underscored the significance of P. aztecorum in the broader context of hallucinogenic species. By distinguishing its unique characteristics and its role within traditional ceremonies, he cemented its place not only within the taxonomy of psilocybin-producing fungi but also within the cultural heritage of the regions it inhabits.

Description and Identification

The enigmatic Psilocybe aztecorum, a species nestled within the vast genus Psilocybe, presents a fascinating subject for mycologists and ethnomycologists alike. This chapter delves into the physical and microscopic characteristics that distinguish P. aztecorum from other psilocybin mushrooms, providing a comprehensive guide for identification.

Physical Characteristics


  • Size and Shape: The caps of Psilocybe aztecorum are convex to bell-shaped, often developing a pronounced umbo with age. They typically reach diameters of 1.5 to 2 cm, showcasing the mushroom’s delicate structure.

  • Coloration: Exhibiting a hygrophanous nature, the cap color varies significantly with moisture content. Fresh caps can appear dark yellowish brown, shifting to a lighter, straw-colored hue when dry. This color change is a key identification feature.

  • Surface Texture: When moist, the caps are slimy to the touch, with translucent striations visible along the margins. As they dry, the texture becomes markedly smoother.


  • Dimensions: The slender, cylindrical stems can grow up to 7.5 cm in length, with a thickness ranging from 3 to 4 mm. This aspect contributes to the mushroom’s fragile appearance.

  • Color and Texture: Stems are initially whitish to greyish, becoming dark violet brown with age. The presence of dense, white rhizomorphs at the base is a distinctive characteristic rarely observed in other Psilocybe species.


  • Attachment and Color: The gills are adnate to adnexed, starting light violet gray and darkening to a violet brown as the spores mature. The edges may remain lighter, providing a subtle contrast.

Microscopic Features


  • Shape and Size: Spores of P. aztecorum are elongated-ellipsoid, typically measuring 12–14 µm in length. Their dark violet brown color under the microscope is indicative of their maturity.

  • Germ Pore: A prominent broad germ pore is present, characteristic of many Psilocybe species but varying in size among them.


  • The four-spored basidia measure 24–33 µm in length, supporting the production of the species’ spores. Their hyaline to yellowish appearance under the microscope is notable.


  • Cheilocystidia: Found on the gill edges, these elements are fusoid-ampullaceous, contributing to the mushroom’s ability to disseminate spores.

  • Pleurocystidia: Scattered and similar in shape to cheilocystidia, they are indicative of P. aztecorum’s capacity for spore production.

Similar Species

Psilocybe aztecorum is part of a complex of species within the genus Psilocybe that are known for their psychoactive properties. Its closest relatives share many physical and microscopic features, yet P. aztecorum distinguishes itself through its unique combination of cap coloration, stem characteristics, and spore morphology. Other similar psilocybe species such as Psilocybe mexicana and Psilocybe baeocystis, share overlapping habitats and appearances but can be differentiated by their spore size, cap texture, and reaction to chemical tests.

Habitat and Distribution

The habitat and geographical distribution of Psilocybe aztecorum offer a captivating glimpse into the ecological niche that this sacred mushroom occupies.
