Extract from Wikipedia article: Agrocybe pediades, commonly known as the common fieldcap or common agrocybe, is a typically lawn and other types of grassland mushroom, but can also grow on mulch containing horse manure. It was first described as Agaricus pediades by Swedish mycologist Elias Magnus Fries in 1821, and moved to its current genus Agrocybe by Victor Fayod in 1889. A synonym for this mushroom is Agrocybe semiorbicularis, though some guides list these separately. Technically it is edible, but it could be confused with poisonous species, including one of the genus Hebeloma.
Agrocybe pediades is a species of fungus that belongs to the family Strophariaceae. In St. Petersburg, Leningrad Oblast, and north-western Russia, it typically grows in fields, meadows, and along roadsides, often in association with grasses and other herbaceous plants. Fruiting bodies are usually found from June to September, with a peak in July and August. The cap is 2-5 cm in diameter, bell-shaped to convex, and brown to grey-brown in color, while the stipe is 3-6 cm long and 0.5-1 cm thick, cylindrical, and often curved. Spores are brown, elliptical, and measure 8-11 x 5-6 μm. The fungus is considered rare to occasional in the region, but can be locally common in suitable habitats.
