Royal Trumpet mushrooms are medium to large in size and are easily identified by their thick cylindrical stem and their small, flattened cap.  The small, smooth caps are grey to brown and have rounded, curved edges. Underneath the cap, the stem and cap are joined by off-white, thin, short, gills. Royal Trumpets, when cooked, the mushrooms have a savory umami flavor, a soft, crunchy texture, and a mild flavor reminiscent of abalone. They are native to Mediterranean regions of Europe, the Middle East, and North Africa, but also grown in many parts of Asia.
