Description
This small agaric is producing characteristic rings in turf. It has a bell-shaped to convex cap, which becomes flatter with a broad umbo with age.

Cap at first convex, then flat to cup shaped with a low central hump that is often a darker shade. Color varies from light beige to brown yellow. The margins are usually crinkled and almost transparent and streaky in damp weather. They turn lighter in dry weather, and regain their color in more humid conditions. The flesh is whitish buff, thick at the center, otherwise thin. Gills free, sparse, and convex in the center with horizontal ridges. Creamy white at fist, becoming ochraceous-cream, fairly broad and distant. Spores off-white. Stem tall, colored as cap, smooth or finely scurfy, slender, more or less equal, whitish downy at the base and slightly rooting, stiff. The mushroom has no ring.

Similar species The poisonous Clitocybe dealbata is found in the same grassy habitat. It is distinguished by its decurrent gills. Can also be mixed up with the very poisonous mushrooms Clitocybe rivulosa and Clitocybe dealbata.
