Strobilomyces dryophilus is a species of bolete fungus that grows in association with trees, typically oak. In East and Central Texas, it fruits from May to October, often in sandy or clay soils under post oak, live oak, and other Quercus species. The cap is 3-8 cm wide, dry, and velvety, ranging in color from dark brown to nearly black, with a distinctive reticulate pattern of white or pale yellow veins. The pore surface is yellowish-brown to olive-brown, and the stalk is similarly colored, often with a reticulate pattern.
