🔬 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.

Saffron bolete

Cap 5–12 cm, hemispherical in young mushrooms, then cushion-shaped. Color yellow-brown, ocher-yellow, darkening to brown with age. The surface is matte, dry, slightly sticky in wet weather. In mature mushrooms it may crack finely.

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.

Saffron bolete

Hymenophore tubular, with a slight notch near the stem. Yellow when young, olive-yellow to brown in mature mushrooms. Pores small, angular, quickly darkening to gray-violet 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.

Saffron bolete

Stem 6–15 cm tall, 1.5–3 cm thick, cylindrical, sometimes bulbous at the base. Yellow-brown, covered with characteristic dense grayish-brown scales — a typical feature of the genus Leccinellum.

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.

Saffron bolete

Flesh bright yellow in young mushrooms. When cut it darkens DRAMATICALLY: within a few seconds it turns yellow, after a minute gray-violet, after a few minutes almost black. This is a normal reaction of the species, not toxicity.

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.

Saffron bolete

Smell faint, pleasantly mushroomy. Taste mild, without bitterness.
