This genus can look like an Agaricus but the gills remain white. They have a ring on the stipe (stalk) which may be moveable. Many Leucoagaricus species have not yet been described and named.
Leucoagaricus leucothites (Vittad.) Wasser
These white mushrooms can be found often growing in fairy rings in grassland, and at a distance look like the edible field mushroom. However, once picked it is easy to tell these ones apart as they have white gills and a delicate white collar on the stalk.
Some people find these make them ill if eaten.
Found growing on a very rotten log in beech forest.
