"Stuntz’s Psilocybe", "Stuntz’s Blue Legs", "Blue Ringers", "Washington's Blue Veil"

Psilocybe stuntzii or “Blue Ringer” also commonly known as “Stuntz’s Blue Legs“, is a species of magic mushroom of the Hymenogastraceae family. It was named in honor of American mycologist Dr. Daniel Elliot Stuntz, who made the type collections, and focused his life-long studies on the Inocybe genus.
Psilocybe stuntzii or “Blue Ringer was originally identified by Dr. Stuntz growing on the University of Washington campus. It had a particularly pronounced bluish tinged. Even though its flesh readily bruises blue, the P. stuntzii magic mushroom is considered the least psychoactive of the bluing Psilocybes.
It is a synonym of Psilocybe pugetensis, and has a more slender and pale variety, named P. stuntzii var. tenuis.

Often found fruiting in prodigious colonies along the Pacific Northwest coast, this hallucinogenic mushroom is placed in the section Stunzae (see P. subaeruginascens, also from that section).Taxonomically similar species include Psilocybe caeruloannulata, reported from Uruguay and Brazil, and Psilocybe jacobsii, collected in Oaxaca, Mexico

Nonetheless its overall appearance being dangerously close to that of the deadly Galerina autumnalis, it is strongly advised not to hunt the Blue Ringer specie for its entheogenic properties.

Visual Description

• Cap: 1.5-5cm broad. Obtusely conic at first, soon expanding to broadly convex with an umbo, nearly flattened or plane in age, margin lifting in very mature specimen. Margin striate translucent, halfway to the disk when wet; decurved, then getting straight, soon lifting, undulating and often eroded with very old age. Coloration dark brown, lighter at margin, darker at disk. Margin often olive greenish. Cap hygrophanous, fading to yellowish brown to pale yellow in drying. Note some varieties are not as hygrophanous and tend to be more olive yellowish brown. • Gills: Attachment adnate to adnexed. Close, moderately broad. Color is pallid when young, soon turning brownish, very dark when mature. • Stem: 30-60 mm long by 2-4 mm thick. Almost equal, slightly thicker at apex, often curved, base is inflated. Color pale yellowish brown. Surface dry, with fibrils at the annular zone, sometime leaving fragile annulus ring. Annular zone darkened by spores at maturity. Flesh bruising bluish. • Spore print: dark purplish brown • Microscopic features: 9-10.5 by 5.5-7.5 µ. • Taste and odor: believed to be farinaceous.


MILD < 0.25% MODERATE 0.25% - 0.75% By dry weight, P. stuntzii is said to be the weakest of the bluing Psilocybes clade. Weakly to moderately active: 0-0.36% psilocybin, 0- 0.12% psilocin (Beug et Bigwood, 1982b). Repke et al. reported 0.02% baeocystin.

Habitat Origin

Fruiting season is autumn to early winter. Prolific along coastal regions, especially Oregon, Washington, and British Columbia. Grows in group, often in prodigious colonies, on conifer wood chips, in soils rich in woody debris, in fields, in newly placed lawns, found along roads, and in gardens.


As this strain is said to be weak, we speculate the hallucinogenic effects to be mild. Effects would include euphoria, visual stimulation with slight tracing effects, dilated pupils, enhanced heartbeat, occasional nausea.
