Agaricus arvensis

Agaricus arvensis, a wild mushroom commonly known as the horse mushroom, is an edible species, closely related to the white button mushroom found in the produce section of groceries. It’s gills change color from pink to deep brown as it ages and it has a lovely anise aroma when freshly picked. The white bits around the edges are remnants of its universal veil. Never consume wild mushrooms without a positive ID!
