AI-generated summary of observations

Observations of Inocybe napipes in Leningrad Oblast and north-western Russia reveal its presence in specific habitats. The fungus was found in the area of a peat swamp in Sosnovka Park, Saint Petersburg, growing among moss on peat soil. Multiple sightings occurred in this park, with records on June 30, July 6, and August 4, 2017. These observations suggest that Inocybe napipes thrives in moist, acidic environments with abundant organic matter, such as peat swamps and areas with moss-covered peat soil. The repeated sightings in Sosnovka Park indicate a possible preference for this type of habitat, highlighting the importance of preserving these ecosystems to support the growth and diversity of fungal species like Inocybe napipes. The fungus's growth was documented over several weeks, indicating its persistence in the area during the summer months.
