Notes On The Genus Psathyrella Apr 2026

: 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.

: Species like Psathyrella piluliformis grow in clusters on decaying wood.

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. NOTES ON THE GENUS PSATHYRELLA

Species within Psathyrella typically share several defining physical traits:

: 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

: 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 species worldwide, though many remain poorly understood or await formal description. The genus Psathyrella is a large and complex

: Gills are typically adnate and produce a dark spore print , ranging from purplish-black to dark brown.
