AI-generated description

Psathyrella prona 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 wrinkled or veined surface. The cap is usually brown to dark brown in color, while the gills are crowded and attached to the stem. The stem itself is slender, hollow, and typically the same color as the cap. In St. Petersburg, Leningrad Oblast, and north-western Russia, Psathyrella prona has been found growing in a variety of habitats, including deciduous and mixed forests, woodland edges, and grasslands, often in association with mosses, lichens, and other fungi. It typically fruits from summer to autumn, particularly after rainy periods. The species is considered to be relatively rare in the region, but can be locally common in certain areas with suitable habitat conditions.

AI-generated summary of observations

Observations of Psathyrella prona in Leningrad Oblast and north-western Russia reveal the fungus grows near roadsides, as seen in Dibuny, north-west of Saint Petersburg. On July 15, 2017, specimens were found alongside Inkcap mushrooms, specifically Coprinellus angulatus. The Psathyrella prona mushrooms were described as small and brittle-stemmed, with observations including close-up examinations. Multiple collections were made from the roadside, indicating a possible preference for this habitat. The fungus was observed to be growing in this specific region of Russia, providing insight into its distribution and growth patterns in north-western Russia. The observations suggest Psathyrella prona thrives in roadside environments, at least in the Dibuny area.
