🔬 Morphology

Cap

Larch bolete

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.

Weeping bolete

Cap 3-10 cm across, hemispherical with an inrolled edge when young, becoming convex-flat with time. The color is yellow-chestnut, honey-brown, reddish-brown, darker when young, fading to ocher-yellow with age. The surface is very slimy in wet weather, smooth, shiny. Glossy in dry weather. The skin peels easily from young mushrooms, with more difficulty from old ones.

Hymenophore

Larch bolete

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.

Weeping bolete

Pores and tubes — the tubes are attached to the stem or slightly decurrent. In young mushrooms they're pale yellow, with characteristic tiny whitish droplets of milky juice. Over time the droplets dry, leaving granular brown dots on the tubes. With age the tubes turn yellow-olive. The pores are small, the same color as the tubes. Spore print ocher-brown.

Stem

Larch bolete

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.

Weeping bolete

Stem 4-8 cm tall, 1-2 cm thick, cylindrical, even, without a ring. The color is yellowish, and in the upper part with characteristic tiny yellow-brown granular dots — dried droplets of milky juice. This is the main diagnostic feature of the species.

Flesh

Larch bolete

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.

Weeping bolete

Flesh firm when young, softening with age, creamy yellow. When cut it doesn't change color — unlike the velvet bolete. The smell and taste are mild and pleasant, with a slightly fruity note.

Smell

Larch bolete

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

Weeping bolete

Pleasant and mushroomy with a light fruity note — especially in young ones.
