Notes On The Genus Psathyrella Apr 2026

: Identification often hinges on microscopic characters like cystidia (sterile cells on the gills or cap) and specific spore measurements . Ecological Niche

: Modern DNA sequencing (ITS and LSU rDNA) has revealed that traditional morphology-based classifications are often artificial. This has led to the reclassification of some former Psathyrella species into genera like Parasola or Coprinopsis . NOTES ON THE GENUS PSATHYRELLA

: There are estimated to be over 500–600 species worldwide, though many remain poorly understood or await formal description. : Identification often hinges on microscopic characters like

: Much of the foundational work on European species was published by Emile Kits van Waveren in his series "Notes on the Genus Psathyrella" and his 1985 monograph. : There are estimated to be over 500–600
