: Species like Psathyrella piluliformis grow in clusters on decaying wood.
: 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
These fungi are primarily , meaning they decompose organic matter. Their habitats vary widely: Terrestrial : Many grow directly on soil.
: There are estimated to be over 500–600 species worldwide, though many remain poorly understood or await formal description. : Species like Psathyrella piluliformis grow in clusters
Species within Psathyrella typically share several defining physical traits:
: 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
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.
