Observation 56617: Psilocybe zapotecorum R. Heim
When: 2010-10-15
Collection location: Jalisco, Mexico [Click for map]
( 1400m)
No herbarium specimen

Notes: This collection has oddly shaped cheilocystidia, which is often long and thin, sometimes with a ball at the apex. It can also resemble twisted strings. The pleurocystidia is often bottle shaped, with a ball at the apex.

I think all the unlabeled microscopy is cheilocystidia, but some plerocystidia may have snuck in there.

Very fragile stems.

Recognized by sight: This is within the range of what I call zapotecorum. The description from The Genus Psilocybe indicates that the cystidia can have funky shapes. They aren’t too far off from the drawings, though they have a more acute apex. The long cystidia are interesting, similar to the crazy cystidia that define P. villarrealiae.
Used references: Gaston Guzman said that P. zapotecorum stems are sometimes tough and sometimes fragile.
Based on microscopic features: Thin walled elipsoid spores in both front and side view.
Based on chemical features: Staining blue.
