Observation 21281: Psilocybe ovoideocystidiata Guzmán & Gaines

When: 2006-02-15

Collection location: Balboa Park, San Diego, California, USA [Click for map]

Who: Christian (Christian Schwarz)

No specimen available

I was pretty confused by these. They sort of look like what some people call “Stropharia aeruginosa” under oak around San Diego, but the gills looked too light (reddish-brown), and they were rather clustered.

Under Bear’s Breeches (Acanthus spinosus) in woodchip mulch.

Those look like a bluing Psilocybe. They resemble P. subaeruginascens sp. aff. that has recently become recognized in the Bay Area, or maybe the species that my friend in LA has been finding.

Here is the interesting Bay Area subaeruginascens-like species, with some confusion and debate over whether any blue Stropharia may have been in the mix.

And here are some threads with good photos of the Psilocybe species from LA.
