Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Brazil, Colombia, Ecuador, and India. Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Stump Brittlestem

Habitat

Typically found in forest floors, decomposing wood, and soil ecosystems.

Range

Widely distributed across Asia (Taiwan), Europe (5 countries), North America (United States), and South America (Brazil).

Common Stump Brittlestem

<em>Psathyrella piluliformis</em>, the common stump brittlestem, is a saprotrophic basidiomycete fungus in the family Psathyrellaceae, order Agaricales. It has a broad distribution across Asia, Europe, and the Americas, typically found growing in dense clusters on or near the stumps and buried roots of deciduous trees, particularly oaks and beeches, from autumn through to early winter. The fruitbodies are hygrophanous, changing colour dramatically depending on moisture content, ranging from pale buff when dry to a rich honey-brown when wet. <em>Psathyrella piluliformis</em> plays an important ecological role as a wood decomposer, facilitating the breakdown of lignin and cellulose and contributing to nutrient cycling in forest ecosystems. The fragile, brittle gills and thin-walled spores are characteristic of the genus. Biological traits including average mycelial lifespan, fruiting body dimensions under natural conditions, and specific substrate preferences remain poorly documented. The species is assessed as Least Concern by the IUCN, reflecting its wide distribution and apparent abundance across temperate woodland habitats in the Northern Hemisphere and beyond.
