Extract from Wikipedia article: Tricholoma imbricatum is a species of agaric fungus in the family Tricholomataceae. Commonly known as the matt knight, it is found in Europe and North America, where it grows on the ground in coniferous forests. Fruit bodies have a brown to reddish-brown cap up to 9 cm (3.5 in) in diameter, and a stipe that is 3.5 to 4.5 cm (1.4 to 1.8 in) long by 1.0 to 1.2 cm (0.39 to 0.47 in) thick. The gills are initially whitish in color before developing reddish-brown spots.

AI-generated description

Tricholoma imbricatum is a medium-sized agaric fungus with a brown to greyish-brown cap, often with darker scales, and white to cream-colored gills. It grows in association with coniferous trees, particularly spruce and pine. In St. Petersburg and Leningrad Oblast, it typically fruits from August to October in moss-covered forests and heathlands. In north-western Russia, the species is widely distributed and can be found in similar habitats, often forming mycorrhizal relationships with native tree species. The fungus is considered edible, but its culinary value is variable.

AI-generated summary of observations

Observations of Tricholoma imbricatum in Leningrad Oblast and north-western Russia reveal that the fungus grows in various habitats. Near Kavgolovskoe Lake, north of Saint Petersburg, the mushrooms were found on September 21, 2016. They were observed growing in two distinct locations: near the lake and on a roadside adjacent to the lake. The presence of Tricholoma imbricatum in these areas suggests that the species can thrive in a range of environments, from lakeside habitats to disturbed areas like roadsides. The September fruiting period indicates that the fungus is active during late summer to early fall in this region. These observations provide insight into the ecological preferences and distribution of Tricholoma imbricatum in north-western Russia. The species' ability to grow in different habitats highlights its adaptability and potential for widespread distribution in the region.
