Proposed Names

23% (6)
Based on microscopic features: Spores length: 7.7-9.8 microns, pale yellowish brown.
Cheilocystidia length: (15.5)18.5-30.3 microns, rarely bifurcate.
Pleurocystidia very scarce and scattered, easy to miss or discount as anomolous.
Basidia, both 2 and 4 spored observed.
Despite what appears to be the occasional pleurocystidia, all other features match well with Psilocybe caerulipes.
Based on chemical features: Blue staining
-13% (4)
Based on microscopic features: Presence of pleurocystidia with swollen apices, wide spores.

What I thought were anomalous pleurocystida are actually rather typical for Psilocybe quebecensis. The spores are also too wide for Psilocybe caerulipes.
