Appearance
The fruit body is roughly spherical with a somewhat flattened top, and has a thick, stem-like base; it attains a diameter of 2–7 cm. Its color is ochre or dingy brown, and the surface is covered with scaly warts that eventually slough off to leave a relatively smooth surface. The thin flesh underneath the peridium stains pink to red when the fruit body is cut open. The peridium is thin a fragile when dry, and cracks irregularly to form a large opening. The internal spore-bearing tissue, the gleba, is initially white, but becomes light brown and powdery after the spores mature. The spores are spherical, and covered with minute warts or spines, and measure about 12 μm in diameter.The fruit bodies are edible when the gleba is still firm and white.
On the other hand, S. verrucosum appears to cause poisoning symptoms similar to Scleroderma citrinum at least in some people, so it cannot be recommended for consumption.
Habitat
"Scleroderma verrucosum" is a mycorrhizal species. Fruit bodies grow in the soil in nutrient-rich, sandy soil, often in deciduous forests. The species has been found in Africa, Asia, Australia, Europe, North America, and South America.The species was featured on a Paraguayan postage stamp in 1985.
