Extract from Wikipedia article: Inocybe lacera (commonly known as the torn fibrecap) is a poisonous species of mushroom in the genus Inocybe. Its appearance is that of a typical "little brown mushroom": small, brown and indistinct. However, it is distinguishable by its microscopic features, particularly its long, smooth spores. As with many other species of Inocybe, I. lacera contains the poisonous chemical muscarine which, if consumed, can lead to salivation, lacrimation, urination, defecation, gastrointestinal problems and emesis. Found in Europe and North America, it typically grows in autumn in mixed woods, favouring sandy soil. There are several documented subspecies in addition to the main I. lacera var lacera, including the dwarf form I. lacera var. subsquarrosa and I. lacera var. heterosperma, found in North America.
Inocybe lacera is a species of mushroom in the family Inocybaceae. It has a bell-shaped to conical cap that is 1.5-4 cm in diameter, initially pale brown to grey-brown, and later becoming more pale. The gills are crowded, adnate to emarginate, and pale grey-brown to sepia. The stem is 2-6 cm long, 0.3-0.8 cm thick, and fibrillose. In St. Petersburg, Leningrad Oblast, and north-western Russia, Inocybe lacera typically grows in deciduous and mixed forests, often with birch, aspen, or willow, from July to September. It is considered a relatively rare species in the region.

Russia, May 29, 2021Plyazhnaya Ulitsa, 27, Sankt-Peterburg, Russia, 197706Observations of Inocybe lacera in Leningrad Oblast and north-western Russia reveal that the fungus grows in various locations, including Dibuny, Botanic Gardens of Komarov Botanical Institute, and overgrown sandy beaches near Sestroretsk. The mushrooms were found on different dates, specifically August 9, 2016, September 24, 2016, and May 29, 2021. They appeared as little brown mushrooms or small brown fibrecap mushrooms, with some specimens displaying torn fibrecaps. Close-up observations showed detailed features of the mushrooms, while underside views revealed additional characteristics. Young specimens were also observed, indicating the presence of multiple growth stages. The fungus seems to thrive in sandy beach environments and botanical gardens, suggesting adaptability to different habitats in the region. The observations provide valuable insights into the distribution and morphology of Inocybe lacera in north-western Russia.
