Cap 1.5 to 4cm across and 3 to 4cm tall, the pestle-shaped to pear-shaped fruitbody of the Stump Puffball is at first covered in short pyramidal warts. White intially , the skin turns brown and a dark area develops at the apex, which ultimately opens to release the spores.

SporesRound or subglobose, smooth, 3.5-4µm in diameter.
Spore massOlive-brown, eventually becoming dark brown when fully mature.
