: 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 .
: Caps are often thin, fragile, and hygrophanous , meaning they change color significantly as they dry. They frequently feature a distinct, sometimes appendiculate, veil that may disappear with maturity. NOTES ON THE GENUS PSATHYRELLA
: Some species specialize in growing on the dung of animals like cows or horses. : Modern DNA sequencing (ITS and LSU rDNA)
The genus Psathyrella is a large and complex group of dark-spored, saprotrophic fungi within the Psathyrellaceae family . Identifying these species often requires detailed microscopic analysis, as many possess nearly identical macroscopic features. Historical and Modern Taxonomy
: Identification often hinges on microscopic characters like cystidia (sterile cells on the gills or cap) and specific spore measurements . Ecological Niche
: Psathyrella aquatica is a rare example of an underwater-fruiting mushroom found in rivers. Historical and Modern Taxonomy
