Psilocybe cyanofibrillosa

Cap: 1-4 x 3.5 cm broad. Conic to convex to broadly convex. Plain in age. Deep chestnut brown, hygrophanous, fading to pale tan or yellowish brown or grayish white in drying. Viscid when moist with a separate pellicle. Gills: Adnate to adnexed. Light grayish when young becoming purplish brown in age with white edges. Stem: 30-70 mm long x 2-4 mm thick. Straight, enlarged at base with fibrills. Bruising blue when damaged. Spores: (9) 9.5-11 (12) x (5.5) 6-6.6 (7)m. Sporeprint: Purplish brown. Habitat: Scattered to gregarious among bush lupines in alder and willow wood chips and bark mulch. Common among rhododendron gardens and nurseries and flood plains near river estuaries. Distribution: From northern California (Eureka/Arcada) north to British Columbia, Canada. Season: September to December. Dosage: 1 large specimen, 2 to 5 small specimens. High in psilocin and low in psilocybin. Loses over 70% or more of their potency in drying. Comment: A few hundred pounds of this species mixed with Psilocybe cyanescens was collected from mulch piled along side of I-5 highway on both sides of the road between Eureka and Arcada, California. I myself have only collected this species a few times in a twenty year period.
