Extract from Wikipedia article: Agaricus silvaticus (or Agaricus sylvaticus), otherwise known as the scaly wood mushroom, blushing wood mushroom, or pinewood mushroom, is a species of mushroom often found in groups in coniferous forests from early summer, or September through to November in Europe, North Africa and North America.
Agaricus sylvaticus is a species of mushroom found in northern Europe, including north-western Russia. In St. Petersburg and Leningrad Oblast, it typically grows in coniferous and mixed forests, often associated with spruce and pine trees. Fruiting bodies usually appear from July to October, with caps ranging from 3-8 cm in diameter, brown to reddish-brown in color, and stems 4-7 cm tall, 1-2 cm thick, and fibrillose. The species is considered edible and is occasionally collected for food in the region.

AI-generated summary of observations
In Leningrad Oblast and north-western Russia, observations of Agaricus sylvaticus have been recorded. On August 22, 2016, scaly wood mushrooms (Agaricus sylvaticus) were found in Pavlovsk Park, a suburb of Saint Petersburg, Russia. The species was observed growing in a wooded area, likely in association with trees such as birch or pine. The caps of the mushrooms were noted to be scaly, with a brownish-gray color, and the stems were white with a ring. The size of the mushrooms varied, but most were around 5-10 cm in height. The observation suggests that Agaricus sylvaticus is present in the region and can thrive in wooded areas with suitable habitat. Further observations are needed to determine the full range and distribution of this species in north-western Russia. The presence of this species may indicate a healthy fungal community in the area.
