This mushroom has been a little elusive on my wild mushroom forays. Its dark color and thin, ruffled edges make it a bit difficult to spot on the forest floor. But finding some black trumpet mushrooms is a treat, because they are very delicious. If you aren't a mushroom forager, you can find these at your local gourmet fungi distributor, or online.Black trumpet mushrooms are cornucopia-shaped, with ruffled lips, and a dark brown to dark purplish black in color. They are thin and papery. In spite of their fragile appearance, they have a lot of flavor. They are delicious sauteed in a little butter, and they dry very well. They do very well in soups and risottos and have a very deep flavor.
