Calocybe gambosa, commonly known as St. George's mushroom, is an edible, medium to large, fleshy, cream coloured mushroom. It grows mainly in fields, grass verges and roadsides, but also less frequently appearing in mixed woods.

Cap white-creamy coloured to bright yellow, often with a brownish tinge. At first sub-spherical, becoming expanded and irregularly convex with an incurved margin. Gills sinuate, white and crowded. The flesh is thick and soft and has a mealy or cucumber smell. The spore print is white to pinkish white. Stem whitish, smooth, bulky at the base. The mushroom has no ring.

Similar species include the deadly poisonous Inocybe erubescens. Spring fruiting white Entoloma species are distinguished by pink spore deposits and pink mature gills.

If you plan to collect fungi to be eaten, misidentified mushrooms can make you sick or kill you. Never eat a mushroom that you are not 100% sure is edible. Use many resources, and be skeptical of your own conclusions. Please consider that many mushrooms take years of experience to identify reliably.
