AI-generated summary of observations
Observations of Lentinus brumalis in Leningrad Oblast and north-western Russia show that the fungus grows on various substrates, including rotten logs, fallen willow and birch trees, wood litter, and peat in swampy areas. The mushrooms were found in different locations, such as Orekhovo, Toksovo, Lavriki, Lisiy Nos, Sosnovka Park, Pesochnaya, Dibuny, and Lembolovo, all north or west of Saint Petersburg. The fungus was observed during various times of the year, from October 2016 to June 2017, with multiple sightings in March and April 2017. The mushrooms were often found on decaying wood, suggesting that Lentinus brumalis is a saprotrophic species that plays a role in decomposing organic matter in these ecosystems. The observations also highlight the fungus's ability to grow in different environments, including forests and swampy areas.
