: Identification often hinges on microscopic characters like cystidia (sterile cells on the gills or cap) and specific spore measurements . Ecological Niche
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.
: 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
: Species like Psathyrella piluliformis grow in clusters on decaying wood.
: Some species specialize in growing on the dung of animals like cows or horses. : Identification often hinges on microscopic characters like
The taxonomy of Psathyrella has undergone significant revision:
: 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. : Caps are often thin, fragile, and hygrophanous
These fungi are primarily , meaning they decompose organic matter. Their habitats vary widely: Terrestrial : Many grow directly on soil.
