Leucoagaricus barssii is a species of mushroom that grows in fields, meadows, and along roadsides. In East and Central Texas, it typically fruits from May to October, producing small to medium-sized caps that are white to cream-colored with pinkish-brown discoloration. The stems are slender, cylindrical, and often curved, with a ring that may disappear with age. The fungus is found in association with grasses and other herbaceous plants, and its presence is often indicative of rich soil and moist environments.
