Brown Hon Shimeji mushrooms are small to medium in size, growing in tightly packed bunches with convex, rounded, button caps and slender stems. The petite caps are buff to burlap-colored, smooth, and crisp. The ivory to cream-colored stems are slender, averaging 5-7 centimeters in height, and connect to a thick, white, porous inedible base. Brown Hon Shimeji mushrooms have piquant, savory aromas and a sharp, bitter flavor when fresh. When cooked, the texture is tender and chewy with a mild, herbal, and nutty flavor.
