The structure of Psilocybe stuntzii

Belonging to the psilocybe genus gives this beauty some distinct features. 

CapIt starts conical, then gets convex, and has a translucent-striate margin. Its size ranges from 0.5 to 1.5 in. 
GillsThese start off yellowish, then go violet-brown, and they’re responsible for producing a spore print.
StipeThe stem comes in all sorts of lengths, from 0.5 to 3 in. It’s cylindrical and can have some twisty striations. The colors range from whitish to brownish.
VeilIt forms a delicate ring that’s an accessory that darkens as the spores get mature.
StainIf damaged, this mushroom turns blue-green. 
SporesThese are subrhomboid in the face view and subellipsoid in the side view. They’ve got an appendage that’s visible and a yellow-brown hue. 
Spore printThe mushroom leaves a dark violaceous brown spore print. 

Habitat and distribution

It loves to appear in the beautiful landscapes of the western Pacific Northwest. You’ll find it in conifer wood chips, cozy bark mulch, and even new lawns freshly laid with sod, adding a touch of wild charm to the scene.

You can spot it from late July through December, sometimes the sightings continue all year round in Seattle. It occasionally shows up in sunny California, even Santa Cruz. 

This mushroom was once a common sight, gracing over 40% of new lawns and mulched areas in the Puget Sound region. These days, it’s become a bit of a wanderer, showing up now and then in well-fertilized, pristine lawns.
