🔬 Morphology

Cap

Blushing wood mushroom

Cap 5-12 cm across, hemispherical to egg-shaped when young, becoming convex-flat with age. Color brown to dark brown, with distinct radially arranged dark brown or blackish-brown scales. The center is solid-colored; toward the edge the scales thin out. The surface is dry, not slimy.

Horse mushroom

Cap 6-20 cm across; in young mushrooms firmly hemispherical to egg-shaped, the margin often rolled under. Later it becomes convex to flat. Color pure white to cream, with subtle yellowish tints in old mushrooms; spots yellow to ocher when touched. Surface smooth, slightly sticky in wet weather, dry and matte in dry weather. Sometimes with fine fibrous scales in the center.

Hymenophore

Blushing wood mushroom

Gilled hymenophore: gills free, crowded. When young they are pinkish-white, and with age they become dark brown to chocolate-blackish. Spore print dark brown.

Horse mushroom

Gilled hymenophore — gills free, crowded. When young — grayish-white, with a pinkish tinge, becoming with age dark brown, chocolate-blackish. Spore print dark brown.

Stem

Blushing wood mushroom

Stem 6-12 cm tall, 1-2 cm thick, cylindrical, slightly thickened at the base. Color white to cream, with fine brownish fibers or scales below the ring. A white membranous ring in the upper part, distinct in young specimens.

Horse mushroom

Stem 6-12 cm tall, 1.5-3 cm thick, thick, fleshy, cylindrical, slightly thickened at the base. Color white to cream. On the upper part — a large membranous double ring with a characteristic "toothed" lower edge (like a cogwheel) — a diagnostic feature of the species.

Flesh

Blushing wood mushroom

Flesh firm, white; when cut it quickly and distinctly turns wine-red, especially in the lower stem. This is the classic protective feature against Amanita. Pleasant mushroomy smell with an almond-anise note.

Horse mushroom

Flesh firm, meaty, white; when cut it slowly yellows in the flesh of the cap and upper stem. Does not redden (unlike A. silvaticus). The smell is a distinct anise-almond — a characteristic feature of the species.

Smell

Blushing wood mushroom

Pleasant and mushroomy, with an almond-anise note. It does not smell of ink or medicine (that would point to the yellow stainer).

Horse mushroom

Distinctly anise-almond, fruity — the most characteristic diagnostic sign. It comes out when you rub the flesh between your fingers. This smell is one of the most pleasant mushroom experiences in field foraging.
