The roughly spherical fruit bodies grow underground. Ranging from 2 to 8 cm (0.8 to 3.1 in) in diameter, they are yellow-brown to darker brown with a fuzzy, furrowed external surface. The inside of the fruit body comprises deeply folded and convoluted tissue with some internal open spaces between them. Young pine truffles ooze a whitish juice when they are cut. The odor of the internal flesh is usually mild, but David Arora has noted the existence of a form in the Western United States that smells similar to fermented cider. Geopora cooperi fruit bodies are edible. The smooth, elliptical or roughly spherical spores measure 18–27 by 13–21 µm and have an oil droplet. The asci (spore-bearing cells) are typically eight-spored. They are arranged as a palisade of cells forming a hymenium that covers the inner surfaces of the internal folds.
