Cap: 1.5-5 cm broad. Obtusely conic, expanding to convex-umbonate
or flat with age. Margin is striate and translucent when moist. Hygrophanous.
Dark chestnut brown while lighter towards the center. Olive-greenish at
times, fading to a pale yellowish brown or pale yellow. Viscid when moist
from a gelatinous pellicle.
Gills: Adnate to adnexed, close to sub distant and moderately
Stem: 30 to 60 mm long x 2-4 mm thick. Enlarged at base. remnants
of a veil remain and are usually bluish from natural injury when the
cap opens. With a whitish pith. Staining blue to blue-green where injured.
Spores: 9-12 x 55-8.3 x5-7.7 µ.
Sporeprint: Dark purplish grayish brown.
Habitat: Growing gregarious to subcespitose clusters and clumps
in conifer wood chips and bark mulch (alder wood), in soils rich in
woody debris, and in new lawns of freshly laid sod.
Distribution: From North of San Francisco to Eugene, Oregon to British Columbia. This species is common in lawns and grassy areas such as parks, fields, or any newly mulched garden area throughout the western region of the Pacific Northwest.
Season: From late July through September in lawns and grassy
areas and from late September through December in mulched garden beds.
This species sometimes occurs all year long depending on warmer el nino weather conditions in the PNW.
Dosage: 20 to 30 fresh specimens, 1/3 fresh ounce or 1-3 dried grams.
Comment: There was a time when this mushroom appeared in over
40 percent of all new lawns and mulched-in garden in areas in the Puget Sound region of the Pacific Northwest.
Due to a disappearance of mixed composts of soils rich in nitrogen and phosphates and came from pasturelands in the
south of Seattle in the Tukwilla-Kent-Auburn areas the region to the northside of Seattle in the Woodinville area
where Meadow Gold Farms provides compost to produce fresh sod from the Bassett and Western Landscapers. Currently
this species is now restricted to appearing sporadically in certain well fertilized and manicured new lawns in the
suburbs of the region. It is also very common in wood chips, preferably alder in the colder weather months of the year.
Recently, a species known to occur in the midwest to east coast of America, Psilocybe ovoideocystidiata, was
discovered in mass quantities fruiting along the West Coast of America. It has been misidentified here as Psilocybe
stuntzii. Both are macroscopically similar so many collections apparently are similar but could be
one or the other species. One noticeable different between Psilocybe stuntzii and Psilocybe
ovoideocystidiata is that the annulus (veil remnants) of Psilocybe ovoideocystidiata is that it's ring stays
where it was when the cap opens but the stipe keeps growing taller leaving the ring fdown the stem. Whereas when the cap
pf Psilocybe stuntzii opens, the veil remains situated close to the opened cap.
