Cap: .7-1.2 (2-5) cm broad. Hemispherical to convex, expanding to broadly convex with age, sometimes conic. Margin translucent-striate when moist. Yellow-umber to cinnamon or reddish-cinnamon.

Gills: adnexed, close and broad. Dull rusty brown with a white fringe along the margin.

Stem: 2.4 mm long x 1-1.4 thick.

Spores: 5.

Sporeprint: .

Habitat: Scattered in grassy areas and fields at times in sphaghum moss.

Distribution: Oregon, Washington and British Columbia, Canada and the northeastern coast of America west to Michigan, Ohio and Pennsylvania.

Season: Spring, Summer and fall.

Comment: Psilocybe smithii macroscopically resembles its close relative, Conocybe cyanopus and it also grows in sphagnum moss only during the early spring rains along streams and riverbanks in grassy areas. I have never personally collected this species. It to has a watery white stem with an enlarged base which immediately stains blue when lifted from the earth and moss. While Conocybe cyanopus never grows taller than 3 inches in height (2.4 cm long), Conocybe smithii tends to produce a shorter stipe fruiting at a length range of 1.5 cm long. I should note that since this mushroom was collected in the Northeast United States, it is possible that this species could be Conocybe cyanopus and not Conocybe smithii.

Dosage: Assuming the small size of this species and its macroscopic similarity to Conocybe cyanopus, I imagine that 40-50 small specimens, 1/3 of a fresh ounce and/or 1 dried gram would be about the same dosage as that of Conocybe cyanopus. This species seems to fruit to a size smaller than Conocybe cyanopus.
