At the base of a cedar tree in green grassy field, kind of chunky in brown and white markings. Growing next to another mushroom much larger in diameter and more round, will post this too.
Lepiota is a genus of gilled mushrooms, in the order Agaricales. Though they have white spores, they are related to the familiar brown spored mushrooms of the genus Agaricus. They typically have rings on the stems, which in larger species are detachable and glide up and down the stem. The cap usually has scales: the colours of the cap, gills and scales are important in determining the exact species, as is sometimes the smell.
