white, becoming ochre-brown, covered with short pyramidial warts which fall off to reveal endoperidium decorated with a reticulate patter; sub-spherical opening by an apical pore, the fertile head tapering down into a distinct, sterile, basal region. Spore mass at first white and firm, becoming olive-brown and powdery. Spores
are pale yellow to olive-brown.
Lycoperdon nigrescens has longer, darker spines in groups, like those of the much longer-spined Lycoperdon echinatum. The surface of both has a similar pattern when the spines fall off.
