Horse Mushroom

Horse MushroomFrequently found near stables, as well as in meadows, where it may form fairy rings, the Horse Mushroom is often found growing with nettles and is one of the most delicious edible fungi. 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, the lower part of the double ring.
