Cap 5 to 10 cm wide, cup-shaped, fine tomentose surface, greasy in moist weather, plain sooty brown to yellowish brown, with a little bit of overhanging cap membrane around the edges. Tubes white at first, then dirty greyish brown. Young tubes turn dirty pink when squeezed. Stem 5 to 10 cm tall and 1 to 2 cm thick, cylindrical with dark brown scales on a whitish ground. Flesh firm, whitish, when cut a dirty pink and then darker in places, faint smell and mild in taste. Common around dwarf birch and in birch scrub on moors inside the fiords; rarer along the coast. Mottled Bolete (Leccinum variicolor) is similar, but the cap is variegated or mottled yellowish brown to sooty brown and often has a greenish tinge, particularly at the base of the stem. Grows in the same spots and is not rare.
