AI-generated description

Psathyrella multipedata is a species of fungus that belongs to the family Psathyrellaceae. It is characterized by its small to medium-sized fruiting bodies, typically growing in clusters or tufts, with caps that are 1-3 cm in diameter, conical to bell-shaped, and brown to greyish-brown in color. The gills are crowded, narrow, and attached to the stem. In St. Petersburg, Leningrad Oblast, and north-western Russia, Psathyrella multipedata has been found growing on rich soil, humus, and decaying organic matter in deciduous and mixed forests, often associated with trees such as birch, aspen, and willow. It typically fruits from late summer to early autumn.

AI-generated summary of observations

The observation of Psathyrella multipedata in Leningrad Oblast and north-western Russia revealed that the fungus grows in clusters. On June 14, 2017, a group of clustered brittlestem mushrooms, identified as Psathyrella multipedata, were found in a ditch near Dibuny, north-west from Saint Petersburg, Russia. The location suggests that the species can thrive in moist environments, such as ditches, which provide ideal conditions for growth. The presence of multiple fruiting bodies in close proximity indicates that the fungus is capable of forming dense clusters, potentially allowing for more efficient spore dispersal and colonization of new areas. Further observations are necessary to confirm the identity of the species and to understand its ecological preferences and distribution in the region. The sighting provides valuable information on the occurrence of Psathyrella multipedata in north-western Russia.
