AI-generated description

Agrocybe dura is a species of mushroom that grows in fields, meadows, and other grassy areas. In St. Petersburg and Leningrad Oblast, it has been found to fruit from June to September, typically in habitats with rich soil and abundant vegetation. In north-western Russia, A. dura is considered a rare species, but it can be encountered in similar habitats, often in association with grasses and other herbaceous plants. The fungus produces small to medium-sized caps that are brown to grey-brown in color, and its stipe is typically slender and cylindrical.
