What color is a pileus?
The pileus is olive-greenish at times, fading to a pale yellowish brown or pale yellow. It is viscid when moist from a gelatinous pellicle, staining slightly greenish-blue when injured or with age.
Effects
The effects of taking Blue Ringers are essentially the effects of taking psilocybin, a psychoactive substance found in many mushroom species and used for recreational, spiritual, and medicinal purposes.
Potency
Blue Ringers are much less potent than most other popular psychoactive mushrooms, requiring doses almost ten times the size of that used for P. cubensis to get the same effect.
Dosage
In general, doses must be much larger than needed for some of the more popular species to get the same effect, however dosage calculations must always be regarded as rough estimates. Psilocybin content can vary, as can human sensitivity to psilocybin. There is not just one dosage for psychoactive mushrooms in any case.
Toxicity, Safety, & Side Effects
There are several different types of risks associated with using Blue Ringers.
Misidentification is another source of risk
First, one of the other psychoactive mushrooms could be mistaken for Blue Ringers, a problem since many of the others are much more potent. The user could end up taking ten times the dose they really want, a recipe for disaster.

Etymology and history
The mushroom is named in honor of mycologist Daniel Stuntz of the University of Washington. It was originally identified growing on the University of Washington campus.
Description
• The pileus is .5–3.5 cm, obtusely conic to convex, expanding to convex-umbonate or flat with age. The margin is translucent-striate when moist and uplifted in age. It is hygrophanous, glabrous, dark chestnut brown while lighter towards the center. The pileus is olive-greenish at times, fading to a pale yellowish brown or pale yellow. It is viscid when moist from a gelatinous pellicle, staining slightly greenish-blue when injured or with age.
Habitat and distribution
Psilocybe stuntzii is found growing scattered to gregarious to cespitose, rarely solitary, in conifer wood chips and bark mulch, in soils rich in woody debris, and in new lawns of freshly laid sod or any newly mulched garden throughout the western region of the Pacific Northwest. It appears from late July through December, being observed all year long in the Seattle area, also reportedly appe…
Edibility
This mushroom is hallucinogenic. Additionally, it closely resembles the highly toxic Galerina marginata, and several poisonings have been attributed to collectors consuming G. marginata after mistaking them for hallucinogenic P. stuntzii.
