Psathyrella pennata is a small to medium-sized agaric fungus with a bell-shaped to conical cap, typically 1-4 cm in diameter, ranging in color from brown to grey-brown, often with a darker center. The gills are crowded, narrow, and pale brown to greyish-brown. The stem is slender, 0.5-2 mm thick, and 2-6 cm tall, usually lighter than the cap. In St. Petersburg, Leningrad Oblast, and north-western Russia, Psathyrella pennata has been found growing in clusters or scattered on rich soil, humus, or decaying organic matter in forests, particularly in areas with coniferous trees, as well as in urban parks and gardens, typically from late summer to early autumn.

Mushrooms Psathyrella pennata in a burned spruce forest in Zakhodskoe (Lounatjoki), 50 miles north from Saint Petersburg. Russia, May 15, 2021Unnamed Road, Leningradskaya oblast', Russia, 188861In Leningrad Oblast and north-western Russia, observations of the fungus Psathyrella pennata reveal its presence in areas affected by fire. On June 28, 2017, brittlestem mushrooms were found on a site of fire in a spruce forest near Kavgolovskoe Lake, as well as near a campfire in the same area. Additionally, they were observed alongside bonfire scalycap mushrooms on an old fire site in a spruce forest on July 14, 2017. Further observations on May 15, 2021, showed Psathyrella pennata growing in a burned spruce forest in Zakhodskoe, alongside stalked bonfire cup mushrooms. The species was also found in abundance in the same burned forest, indicating its ability to thrive in areas with recent fire activity. These findings suggest that Psathyrella pennata is well adapted to colonizing burned areas in north-western Russia.
