Appearance

The fruit body has a convex to flattened brownish cap up to 12 cm across that is covered with brown scales. It can be tinged with pink at the margins and darken with age. The mushroom has yellow-brown spines under the cap that are 5 mm long and 0.3 mm in diameter. They are decurrent to the stem. The pinkish brown stem is 2–12 cm high and 1–6 cm wide, and has a narrower base that is a characteristic greyish green colour. The flesh is whitish and has a bitter taste, rendering the mushroom inedible. The flesh smells farinaceous or like watermelon when cut.
