Brown brittlestem mushrooms Psathyrella clivensis(?) at the bottom of Popovka river canyon in Pyazelevo near Pavlovsk, south from Saint Petersburg. Russia, May 10, 2019Synonyms: Agaricus clivensis, Psilocybe clivensis.
Psathyrella clivensis is a species of fungus that belongs to the family Psathyrellaceae. It is characterized by its small to medium-sized fruiting bodies, typically 1-4 cm in diameter, with a bell-shaped to conical cap that is often umbilicate and has a smooth, moist surface. The cap color ranges from dark brown to pale grey-brown, and the gills are crowded, narrow, and attached to the stem. The stem is slender, cylindrical, and typically the same color as the cap. In St. Petersburg, Leningrad Oblast, and north-western Russia, Psathyrella clivensis has been found growing in groups or clusters on rich soil, often in wooded areas, parks, and along roadsides, typically during the summer and autumn months. It is considered a relatively rare species in the region.

Brittlestem mushrooms Psathyrella clivensis(?) at the bottom of Popovka river canyon in Pyazelevo near Pavlovsk, south from Saint Petersburg. Russia, May 10, 2019Observations of Psathyrella clivensis in Leningrad Oblast and north-western Russia reveal that the fungus grows in specific environments. Notably, brown brittlestem mushrooms, identified as Psathyrella clivensis(?), were found at the bottom of the Popovka river canyon in Pyazelevo near Pavlovsk, south of Saint Petersburg. The observations were made on May 10, 2019, suggesting that the species thrives in this region during late spring. The presence of these mushrooms in the river canyon indicates a preference for humid, possibly shaded areas with rich soil or organic matter. Further observations are needed to confirm the identification and understand the habitat requirements of Psathyrella clivensis in this region. The discovery highlights the importance of exploring diverse ecosystems to document the distribution and ecology of fungal species like Psathyrella clivensis. Similar environments may support the growth of this fungus.
