Extract from Wikipedia article: Psathyrella piluliformis is a species of agaric fungus in the family Psathyrellaceae. It produces fruit bodies (mushrooms) with broadly convex caps measuring 2–5 cm (0.8–2.0 inches) in diameter. The caps are chestnut to reddish brown, the color fading in age and with dry weather. The closely spaced Gills have an adnate attachment to the stipe. They are initially tan until the spores mature, when the gills turn dark brown. Fragments of the partial veil may remain on the cap margin, and as a wispy band of hairs on the stipe. Fruiting occurs in clusters at the base of hardwood stumps.
Psathyrella piluliformis is a small to medium-sized agaric fungus with a bell-shaped cap, typically 1-4 cm in diameter, ranging from brown to greyish-brown in color. It has a slender stem and gills that are crowded and pale brown. In St. Petersburg, Leningrad Oblast, and north-western Russia, Psathyrella piluliformis is commonly found growing in groups or clusters on soil, dung, and decaying organic matter in forests, meadows, and urban areas, particularly from summer to autumn. The fungus is widespread in the region, with frequent records in various habitats, including parks, gardens, and along roadsides.

Common stump brittlestem mushrooms (Psathyrella piluliformis)(?) on wood chips on a forest cutting under power lines near Dibuny, north-west from Saint Petersburg. Russia, September 18, 2017Beloostrovskoye Shosse, 1, Pesochny, Sankt-Peterburg, Russia, 197758Observations of Psathyrella piluliformis in Leningrad Oblast and north-western Russia reveal that the fungus grows in various environments. On a forest cutting in Dibuny, it was found on stumps. Additionally, it was observed growing on mulch and wood chips on a forest cutting near Dibuny. The species seems to thrive in areas with disturbed soil and organic matter, such as forest cuttings and areas under power lines. The fungus was spotted on September 18, 2017, in multiple locations around Dibuny, suggesting it may be common in the region during late summer. The observations highlight the adaptability of Psathyrella piluliformis to different substrates and environments in north-western Russia. Further study could provide more insight into its ecological role and distribution in the area. The species' ability to grow on various materials is notable, indicating a potential for widespread presence.
