I found this Meadow Mushrooms in Micelli Park Roseburg, Oregon USA. Meadow Mushrooms are closely related to the common store bought “button” mushrooms, however, Meadow Mushrooms have more flavor. For more information on these mushrooms look here: This was taken with a Panasonic Lumix DMC-LS70.
Warning never eat any mushroom that you are not 110% sure that it is edible!!!
