Leccinum insigne, commonly known as the aspen bolete or the aspen scaber stalk, is a species of bolete fungus in the family Boletaceae. It was described as new to science in 1966.^{[ citation needed ]} The specific epithet insigne means "distinctive or outstanding". ^[3]

The cap is up to 17 centimetres (6+3⁄4 in) wide, orangish-brown, and semi-fibrillose. ^[4] The tubes are white to yellowish, staining brownish (not blue). ^[4] The stipe is up to 15 cm long and white with dark scabers. ^[4] The flesh is white, sometimes turning gray, and possibly bluish in the base. ^[5] The spore print is tannish. ^[4]

The species is found in North America, where its range extends from eastern Canada south to New Jersey and west to the northern Rocky Mountains. It is a good edible mushroom, ^{[6] [7]} but there have been documented cases of adverse reactions; these range from headaches to gastrointestinal distress, which may or may not be attributed to food sensitivities alone. ^{[8] [9] [10]}
