Summary
This research describes three newly discovered mushroom species from Korea belonging to the genus Psathyrella. The researchers carefully examined physical specimens and documented their unique characteristics using microscopes and standardized methods. This expands our knowledge of fungal diversity in Korea and helps scientists better understand mushroom classification and evolution.
Impacts on everyday life:
• Helps mycologists and naturalists accurately identify mushroom species
• Contributes to biodiversity documentation and conservation efforts
• Advances scientific understanding of fungal evolution and relationships
• Supports potential future discoveries of useful compounds from fungi
• Aids in cataloging and preserving Korea’s natural heritage
Background
The genus Psathyrella is a decomposer characterized by medium size, a membraneous, hygrophanus, straight margined pileus, not extending beyond the gills, an inconspicuous veil, and sooty black spores. Ten species and one variety of Psathyrella were previously known in Korea. Sixty-five exsiccata recorded as Psathyrella spp. were deposited in the Herbarium Conservation Center of National Academy of Agricultural Sciences and investigated.
Objective
To describe and illustrate three new species of the genus Psathyrella discovered in Korea through detailed macro and microscopic analysis.
Results
Three new species were identified and described in detail: Psathyrella pervelatoid, P. koreana, and P. utriformcystis. Each species was characterized by unique morphological features including pileus characteristics, lamellae structure, stipe features, spore characteristics, and microscopic structures like basidia, cystidia and pileipellis.
Conclusion
Three previously unknown species of Psathyrella were discovered and formally described from Korea, expanding the known diversity of this genus. Each new species possesses distinct morphological characteristics that differentiate it from previously known species.
