Psilocybe allenii Spore Syringe

Spores are supplied in sterile aqueous solution using 10 ml Luer-Lok syringes. One 40 mm 16ga needle is provided for each spore-filled syringe.

Psilocybe allenii is a temperate wood-loving Psilocybe species from western North America, taxonomically separate from Psilocybe cyanescens.
While closely related to Psilocybe cyanescens, it can be distinguished by its lack of wavy cap margins, a characteristic feature of the latter. Before formal description, this species was widely discussed in the mycology community under the informal name “Psilocybe cyanofriscosa,” but that name was never validly published.

Psilocybe allenii was formally described in 2012 by Jan Borovička, Alan Rockefeller and Peter G. Werner, and named in honor of John W. Allen, who collected and provided the original type material for study.

For taxonomically related spore material, please check Psilocybe subaeruginosa.

Species: Psilocybe allenii
Habitat: rotting wood, wood chips and woody debris
Climate: temperate
Origin: Western North America

Distribution and ecology
The known range of P. allenii runs along western North America, from British Columbia down toward Southern California, with many observations close to the Pacific coast. It is associated with decomposing woody material, especially wood chips and mulched landscaping beds, making it well-known temperate wood-loving Psilocybe species.

Cap: 1.5–9 cm in diameter, broadly convex to flattened, sometimes with a slight central depression. Yellowish when dry, pale orange brown to caramel brown when moist. Surface smooth and sticky when moist, with a gelatinous cap cuticle that can be peeled. Unlike Psilocybe cyanescens, mature caps of P. allenii usually do not develop the same strongly wavy margin.

Stem: cylindrical and hollow, typically 4–7 cm long and 0.2–0.7 cm thick, with a slightly thicker base. The upper stem is pruinose, while the base is connected to thick white rhizomorphs. Surface smooth to silky fibrillose, white to yellowish with maturity. All parts of the fruit body can stain blue when bruised or handled. Young specimens have a white partial veil that later disappears or remains as a zone on the stem, sometimes colored purplish brown by spores.

Gills: attachment adnate to adnexed, close to moderately crowded. Grayish in young fruit bodies, becoming dark purplish brown to nearly black at maturity as the spores develop.

Spores: dark brown to purple-brown, sometimes with violet tones, produced on cylindrical 4-spored basidia.
