AI-generated description

Tricholoma sulphureum is a medium-sized fungus with a sulfurous-yellow to greenish-yellow cap, often wrinkled or veined, and white to yellowish gills. The stipe is typically the same color as the cap or slightly lighter. In East and Central Texas, it grows in association with various tree species, particularly oak and pine, during late summer and fall. Fruitings are often found in woodland edges, parks, and urban landscapes, where the fungus can form mycorrhizal relationships with native trees. The mushroom's appearance and odor, which is sometimes described as sulfurous or unpleasant, can help distinguish it from similar species in the region.
