🔬 Morphology
Cap
Brown birch bolete
Cap 5–15 cm across, at first spherical or hemispherical, later cushion-shaped. The surface is smooth or slightly wrinkled, dry or a little sticky in wet weather. Color ranges from grayish brown to dark brown, more rarely almost black.
Orange oak bolete
Cap 5–15 cm, hemispherical in young mushrooms, then cushion-shaped. The color is brick-red, blood-brick, darkening with age to brownish red. The surface is matte and velvety, slightly sticky in wet weather. The skin does not peel and overhangs the cap margin as a thin "fringe".
Hymenophore
Brown birch bolete
The hymenophore is tubular. The tubes and pores are white, small in young mushrooms and wider in mature ones. When pressed, the pores turn slightly brownish, but there's never any bluing: unlike in the red-capped scaber stalks, the flesh doesn't blue even at the stem base.
Orange oak bolete
The hymenophore is tubular, free, notched at the stem. White when young, then grayish cream, grayish brown in mature ones. The pores are small and round. They darken quickly when pressed.
Stem
Brown birch bolete
Stem 8–18 cm tall, 1.5–3 cm thick, cylindrical, fairly long and slender compared with the cap. The surface is white or grayish, densely covered with dark, fibrous scales — the hallmark of the genus Leccinum. The stem is firm and fibrous.
Orange oak bolete
Stem 10–18 cm tall, 2–4 cm thick, cylindrical, slightly bulbous at the base. The color is whitish, covered with characteristic dense brown fibrous scales — especially rich in the lower part. The base may have a bluish-green or reddish-brown tint.
Flesh
Brown birch bolete
The flesh is firm and white; when cut it doesn't change colour or turns slightly pinkish, and after a few hours may become a little greyish or brownish. It darkens to grey-black only when cooked. The taste is mild and neutral. The cap skin doesn't peel.
Orange oak bolete
The flesh is white and very firm. When cut it darkens to violet-grey, grey or blackish; the stem base often turns blue-green. The texture is meaty, like the classic red-capped scaber stalk. It gets wormy less readily than the classic one.
Smell
Brown birch bolete
The smell is unobtrusive, pleasant and typically mushroomy. The aroma intensifies with cooking. When dried, the brown birch bolete takes on a rich scent that falls short of porcini but is noticeably better than most other pored mushrooms.
Orange oak bolete
The smell is richly mushroomy and pleasant. The taste is mild and delicate, with a note of forest litter.
