Notes On The Genus Psathyrella (iPhone)

: 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 .

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

: Gills are typically adnate and produce a dark spore print , ranging from purplish-black to dark brown. : Modern DNA sequencing (ITS and LSU rDNA)

Species within Psathyrella typically share several defining physical traits: Ecological Niche : Gills are typically adnate and

: There are estimated to be over 500–600 species worldwide, though many remain poorly understood or await formal description.

These fungi are primarily , meaning they decompose organic matter. Their habitats vary widely: Terrestrial : Many grow directly on soil.

The taxonomy of Psathyrella has undergone significant revision:
