Pileus (Cap): 0.5-3 cm broad. Obtusely conic, becoming conic-campanulate with age. Margin translucent-striate and generally not incurved in young specimens. Chestnut brown when moist, then dark dingy yellow to pale yellow in drying (hygrophanous), often with a pallid band along the margin, and frequently tinged olive green in patches. Surface smooth, viscid when moist from a separable gelatinous pellicle. Flesh thin, pliant, and more or less concolorous with the cap.
Lamellae (Gills): Attachment adnate to adnexed, finally seceding, close narrow to moderately broad. Colour dull cinnamon brown, darkening with spores in age.
Stipe (Stem): 60-80 mm long by 1-2.5 mm thick. Equal above, and slightly enlarged at the base. Surface is covered with appressed grayish fibrils, and powdered at the apex. Whitish to pallid to grayish, more brownish toward the base, blue green where bruised or with age. Flesh stuffed with a tough pith. Partial veil thin to obscure to absent.
Microscopic features: Spores purplish brown in deposit, subellipsoid to subovoid, 9-13 by 5-7 microns. Basidia 4-spored. Pleurocystidia absent. Cheilocystidia 17-36 by 4-7.5 microns, fusiform to lance-shaped, with an elongated neck 1.5-2 microns thick.
Season: Late October to through December after cool, wet weather. Usually fruiting around mid November to December in the Pacific Northwest.
Habitat and Distribution: They like clear cuts that are about 3-10 years old, maybe 3-8 years after replant. If you start finding Hypholoma, you are in a good area to keep looking. Don't let them fool you tho, they are kinda hard to spot. Areas on landings in clear cuts, and then the cuts themselves. On decomposed conifer substrate.
Growth Habit: Small to large clusters or fruiting in troops.
Bruising: Bruising may not appear on this species. It will be hard to see if there is any and it will be towards the base. Although you can check for primordial aborts at the base of a mature specimen and they often bruise blue.
Dosage: 20 to 40 fresh mushrooms or from 2-8 grams dried. moderately weak.
Similar Species: Psilocybe washingtonesis Is a close taxon microscopically and macroscopically but differs from P. pelliculosa by the presence of pleurocystidia.
Other Notes: Are also found in higher elevations of 1000ft-2000ft where clear cuts are more common. A good indicator genus is Hypholoma, Galerina, and Mycena.
