Agaricus arvensis, commonly known as the Horse Mushroom.

Horse Mushroom -


The cap is similar to that of Agaricus campestris (The Field Mushroom). The gills are white at first (when this fungus is most often confused with deadly Amanita genus). They later pass through grey and brown to become dull chocolate. There is a large spreading ring, white above but sometimes with yellowish scales underneath. Viewed from below, on a closed cap specimen, the twin layered ring has a well developed 'cogwheel' pattern around the stipe. This is the lower part of the double ring. The odor is described as like anise. I belongs to a group of Agaricus which tend to stain yellow on bruising.

Distribution and HabitatEdit

It is one of the largest white Agaricus species in Britain and North America. Frequently found near stables, as well as in meadows, where it may form fairy rings, the mushroom is often found growing with nettles (a plant that also likes nutrient-rich soil). It is sometimes found associated with spruce.


Much prized by farmers and gypsies for generations, the 'Horse Mushroom' is one of the most delicious edible fungi.
