This cicada is about 28 to 35 millimeters long and has a wingspan of about 40 to 48 millimeters. The back of the body is grayish yellow with some markings in green, reddish brown or black. There are some light green areas that stand out on the head and thorax. The underside of most of this species is light green or yellowish brown.

The male is characterized with a relatively longer stridulatory organ, while the female is more slender and has a longer ovipositor. On some of them, the surface is covered in a white powder. There is W-shaped green pattern on the back of the thorax. Also, on some individuals, a reddish brown pattern appears, too.

It is convex at first, but gradually becomes flattened. The surface is typically yellow to brown, and has a few dark, hairy scales near the center, arranged radially. The gills are broad and are quite densely arranged. It is white at first, and develops yellowish brown patterns with age. The stipe is 4 to 15 centimeters long and 5 to 15 millimeters in diameter, is yellowish brown to brown, and is fibrillate. The upper part is white while the lower part gets darker with age. There is a broad ring, white to yellow, attached to the upper part of the stipe.

Recently, a plant pathogen that this fungus creates is being used in the artificial cultivation of gastrodia elata, a type of medicinal herb.
