American colors in Sweden

lingonberries, wild Swedish blueberries, and American highbush blueberries., originally uploaded by Vilseskogen.

At the Hötorget market in Stockholm the berries were in season when I was there about 3 weeks ago. WIld lingonberries (red), wild Swedish lowbush blueberries (dark blue), and American highbush blueberries (light blue). Also for sale were large amounts of wild mushrooms, some probably imported from Polish forests, and other seasonal vegetables. Wait, mushrooms are not vegetables. I wonder how USDA classifies mushrooms. They are certainly not fruits, even if they have fruiting bodies with spores.
