Collection location: San Sebastián del Oeste, Jalisco, Mexico [Click for map]
This is the type collection of Psilocybe laurae.
Found in a mesophilic forest along the road from San Sebastian to El Bufo, 5 kilometers from San Sebastian.
I did not observe any pleurocystidia, however Alonso was studying the same collection next to me and he found several. He did not observe any of the long necked pleurocystidia which are depicted in the Psilocybe laurae species description.
All micrographs except the ones labeled “Spores 1000x” were stained with congo red.
In this species, both the pleurocystidia and cheilocystidia absorb much more congo red at the apex of the cystidia. Basidioles absorb congo red uniformly throughout the whole cell. Without congo red, it can be challenging to separate pleurocystidia from basidioles.
