🔬 Morphology

Cap

Red-capped scaber stalk

Cap 6–20 cm across, spherical in young mushrooms, then cushion-shaped. The surface is finely felted or slightly leathery, dry. The color is vivid — brick-red, orange or ginger; in shady spots it may be duller.

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

Red-capped scaber stalk

The hymenophore has tubes. Pores small, round, white at first, then turning brownish. When pressed, the pores turn brownish — this is a normal reaction and does not indicate danger.

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

Red-capped scaber stalk

Stem 8–20 cm tall, 2–4 cm thick, firm, club-shaped at the bottom, cylindrical in the upper part. The surface is white, covered with scales and fibres: reddish, sometimes whitish, in young mushrooms, turning red-brown to blackish with age. The stem base often shows a blue tint, especially where it has been handled. The stem is very hard, almost woody in mature mushrooms.

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

Red-capped scaber stalk

Flesh firm, white; when cut it darkens to violet-grey, grey and eventually almost black; only the stem base often turns blue-green. The darkening also happens during cooking. The taste is pleasant, meaty. In mature mushrooms the stem is very fibrous.
