Leccinum albostipitatum, commonly known as the poplar scaber stalk, is a species of bolete fungus in the family Boletaceae. It is found in Europe and North America, where it grows in mycorrhizal association with poplar trees. The cap is typically 5–15 cm (2–6 in) in diameter, convex to flattened, and has a smooth to slightly wrinkled surface. The color ranges from pale tan to reddish-brown. The stem is 8–15 cm (3–6 in) long and 1–3 cm (0.4–1.2 in) thick, white to pale gray, and covered with dark brown to black scabers (small, rough scales). The pores are small and round, white to grayish, and stain brownish when bruised. The flesh is white, but turns pinkish-gray when cut or bruised. It is an edible mushroom, but should be cooked before consumption.
