Extract from Wikipedia article: Tricholoma virgatum, commonly known as the ashen knight, is a mushroom of the agaric genus Tricholoma. It was first described scientifically as Agaricus virgatus by Elias Fries in 1818, and later transferred to the genus Tricholoma by Paul Kummer in 1871. It is found in the deciduous and coniferous forests of Europe and North America. The mushroom is inedible, and has a bitter and peppery taste and musty odor.

AI-generated description

Tricholoma virgatum is a species of fungus that belongs to the family Tricholomataceae. In St. Petersburg, Leningrad Oblast, and north-western Russia, it typically grows in coniferous and mixed forests, often associated with spruce and pine trees. The cap is 3-6 cm in diameter, grayish-brown to dark brown, and covered with fine, white or pale yellowish fibers. The gills are white or light gray, and the stem is similar in color to the cap, but paler. Fruitings occur from July to October, with peak activity in August and September. This species is considered rare in the region, but can be found in undisturbed forests with rich soil and adequate moisture.

AI-generated summary of observations

Observations of Tricholoma virgatum in Leningrad Oblast and north-western Russia reveal that the fungus can be found in various locations near Saint Petersburg. On September 7, 2016, Ashen knight mushrooms were spotted near Dibuny, west of Saint Petersburg. Two years later, on September 6, 2018, similar mushrooms, identified as possible Tricholoma virgatum, were found in a coastal forest between Lisiy Nos and Olgino, also west of Saint Petersburg. These findings suggest that the species may be present in the region's forests, particularly in areas with coastal influences. The observations were made in September, indicating that the fungus may fruit during this time of year in the region. Further study would be needed to confirm the identity of the 2018 specimens and to fully understand the distribution and habits of Tricholoma virgatum in the area.
