Dissected massive roll-rim mushroom Paxillus obscurisporus(?) in sand on a beach in West Kotlin Nature Reserve in Kronstadt. Saint Petersburg, Russia, September 2, 2018Observations of Paxillus obscurisporus in Leningrad Oblast and north-western Russia reveal its presence in unique environments. On September 2, 2018, a massive roll-rim mushroom, identified as Paxillus obscurisporus(?), was found growing in sand on a beach in the West Kotlin Nature Reserve in Kronstadt, Saint Petersburg. The fungus was observed to be thriving in this coastal habitat, with a notable specimen discovered and subsequently dissected for further examination. The fact that it was found in sand on a beach suggests that Paxillus obscurisporus can tolerate a range of soil types and may be adapted to survive in areas with shifting substrates. Further study is needed to confirm the identification and fully understand the ecological preferences of this fungus in the region. The discovery highlights the diversity of fungal species in north-western Russia.
