Gills adnate or very slightly decurrent, rather distant; white to pale tan, margins of the gills edged with brown. Stem 40-100 x 5-l0mm, rather long, even; slightly paler than cap, white at base. Flesh white, slowly stains pink when cut, as do cap and stem surface. Latex white staining pinkish and drying pinky-brown. Taste mild. Spores subglobose, 8-9.5 x 7-8µ, excluding ornamentation, which forms a partial network of ridges, sometimes connected with fine lines and with large warts and spines 1-2.4μ high. Deposit pinkish buff. Cap surface a layer of short chains of inflated cells. Habitat under spruce in sphagnum bogs. Found in northeastern North America down to Vermont. Season August-October. Edible but not recommended. (Never eat any mushroom until you are certain it is edible as many are poisonous and some are deadly poisonous.) Comment The type variant lacks the dark margined gills and has spore ridges only up to 1µ, high.
