Observation 113977: Psilocybe stuntzii Guzmán & J. Ott
When: 2012-10-20
Collection location: Washington, USA [Click for map]
No herbarium specimen

Notes: See last year’s images of identical fruiting zone: http://mushroomobserver.org/81738?q=m3JS

This is the first sighting of the year for me – and I checked just a couple days ago.

Cap is hygrophanous and has a separable gelatinous pellicle.

Substrate is composed of small, varying-sized wood chips/slices and rich, dark soil – loosely laid. A bryophyte can also be seen not only in the photos but also in the soil immediately surrounding some of the specimens.

Found Oct 20, 2012 – approximately 45 minutes SW of SEA/WA.

Google Earth altitude: 200 feet above sea level.

Gills varying in plain sight color from brown to purple. The flash from the camera will bring out more purple tone.

Stems vary in color from white to whitish-red to dark red. Blue annulus/annular zone found quite consistently but not always.

Purple spore print.

Aroma very faint and not particularly describable for the sake of taxonomy.

No blue coloration noticed except for annulus.

Spores are brown in 5% KOH solution under a compound light microscope (sometimes ranging from clear young spores to gold-brown to dark brown).

Basidia four-spored.

Cheilocystidia very abundant and clustered together – and very frequently branched (not just forked) with multiple branches.

More microscopy notes coming later…

I haven’t found many collection of Psilocybe stuntzii. They vary from collection site in my experience, with the red stipe coloration being more prevalent in mulch collections vs lawn collections.
