Extract from Wikipedia article: Stropharia hornemannii is a species of agaric fungus in the family Strophariaceae. It is found in Europe and North America, where it grows as a saprophyte on rotting conifer wood. The specific epithet hornemannii honors Danish botanist Jens Wilken Hornemann, who made the first scientifically documented collections of the species. Common names for the mushroom include luxuriant ringstalk and lacerated stropharia.
Stropharia hornemannii is a species of fungus that belongs to the family Strophariaceae. It is characterized by its medium-sized to large cap, which is typically 4-8 cm in diameter, bell-shaped to convex, and often has a distinctive umbo. The cap surface is smooth, moist, and varies in color from reddish-brown to grey-brown. The gills are crowded, free from the stem, and have a pinkish-grey spore print. The stem is 4-7 cm tall, 0.5-1.5 cm thick, and has a ring that may disappear with age.
In St. Petersburg, Leningrad Oblast, and north-western Russia, Stropharia hornemannii is commonly found in fields, meadows, and woodland edges, typically growing in association with grasses and other vegetation. It fruits from July to October, often in large groups or rings. The fungus is widely distributed in the region and can be found in various habitats, including urban parks and gardens.
