Bovine bolete or Larch bolete

Cap 3–12 cm, hemispherical in young mushrooms, then flat-convex, almost flat when mature. The color is a dirty yellow-brown, ochre, with a pinkish tinge; in wet weather it's noticeably slimy and shiny. The skin doesn't peel, or peels only with difficulty. In dry weather the cap is matte, sometimes with small cracks at the edges.

Cap 4–10 cm (sometimes up to 15), hemispherical in young mushrooms, then cushion-shaped, almost flat in old ones. Color bright yellow, lemon-yellow, golden-orange, less often rusty brown. The surface is very sticky and shiny — in wet weather it looks literally lacquered. The skin peels off easily and often stretches into strips.

The spore surface is made of tubes, but quite distinctive: the pores are large, angular, irregular, with thin radial walls — they look like honeycomb. The color is dirty yellow at first, greenish-olive with age, and brownish-olive in old mushrooms. The tubes are attached to the stem and often run down it.

Tubes adnate to the stem at first, then notched. Yellowish when young, later grayish- or olive-yellow. Pores small and angular. When pressed they turn pinkish, then brown — a characteristic reaction. In young mushrooms they are covered by a yellowish membranous veil.

Stem 4–8 cm tall, 0.5–1.5 cm thick, cylindrical, often bent and curved — it's rarely straight. The color is the same as the cap or a little lighter. The surface is smooth, with no ring and no net pattern. Near the base it often has a pinkish tinge.

Stem 4–12 cm tall, 1–3 cm thick, cylindrical or slightly widening toward the base. Yellow above, brownish below the ring, with small rusty dots. The ring is white or yellowish, membranous, and breaks down quickly — in mature mushrooms it’s often gone or only a narrow band remains.

The flesh in the cap is yellowish and soft; in the stem it's denser and fibrous. When cut, it doesn't change color or turns slightly pink. In mature mushrooms the texture becomes rubbery, which is why some foragers only take bovine boletes when they're very young.

Flesh yellow, soft, watery in mature mushrooms. When cut it turns slightly pinkish in the cap, and sometimes a bit greenish in the stem. The texture is slimy-fibrous.

The smell is faint, mushroomy, nothing special. The taste is mild, with no bitterness.

Smell faint, mushroomy, with a barely noticeable resinous note. Taste mild, not bitter.
