aspen bolete

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

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, 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.
