Quite a variable mushroom, the cap white or sometimes creamy yellow, and remaining in the button stage for quite a long period. The gills are deep pink, finally darkening to brown. The white stem has a single delicate ring. Similar to the Horse Mushroom (Agaricus arvensis), which is somewhat the larger of the two mushrooms.

Widespread and fairly common throughout Britain. Native.
