Observation 153845: Psilocybe allenii Borov., Rockefeller & P.G. Werner
When: 2013-11-27
Who: nicksodaro
No herbarium specimen

Notes: Stained/bruised blue, hygrophanous cap, hollow stipe, purple brown spores, and large relative to P. cyanescens. Growing on woodchips and dead grass, under pompass grass. I originally found them growing out of grass from underneath rocks. The area was disturbed before the photo taken by the removal of invasive scotch broom growing nearby that provided shade for the mushrooms that grew around these last year.

No annulus on the silky white stipe and rather large for a Stuntzii. No pith inside of the hollow stem. Context of cap does not seem “relatively thin.” Strong bruising blue and forming deep blue to black pits where it is rotting…Also have had them ID’d in the past by a reputable source.

Yep, P. allenii, probably

I concur with the ID, with a vote of “promising”. My slight reluctance to fully commit to the identification is based on the fact that they’re a bit on the old side, and I don’t have any way of looking at the spores or cystidia, and I’ve known rather old P. stuntzii to look remarkably similar, and that’s a species that’s somewhat more common in the Humboldt area than it is southward. Still, I entered the confidence in P. stuntzii as “doubtful” since I don’t think that’s the most likely candidate.
