AI-generated description

Leccinum schistophilum is a rare species of bolete fungus. In St. Petersburg and Leningrad Oblast, it typically grows in association with birch trees, particularly on sandy soils and rocky outcrops. Fruitings are often found in late summer to early autumn. In north-western Russia, the species appears to be restricted to areas with acidic soils and abundant birch cover, with records from coniferous and mixed forests. The cap is typically 4-8 cm in diameter, brown to grey-brown, and often cracked or fissured, while the stem is sturdy, pale brown, and covered in fine, dark brown scales.

AI-generated summary of observations

Observations of Leccinum schistophilum in Leningrad Oblast and north-western Russia reveal that the fungus can be found near Kavgolovskoe Lake, approximately 8-12 miles north of Saint Petersburg. The mushroom has been spotted in this area on multiple occasions, including August 25, 2013, September 20, 2013, and September 23, 2015. Additionally, it has been observed in Sosnovka Park in Saint Petersburg on September 24, 2015, and in Toksovo, a suburb of Saint Petersburg, on July 19, 2016. The fungus appears to thrive in swampy areas near birch trees, with some observations noting its presence in wet environments. The repeated sightings in this region suggest that Leccinum schistophilum is relatively common in Leningrad Oblast and north-western Russia.
