Agaricus squamuliferus or Blushing wood mushroom

Cap 4-9 cm across, hemispherical to egg-shaped when young, becoming convex-flat with age. Color whitish to grayish-cream, with fine brownish or gray-brown radially arranged scales, a distinctive feature of the species. There are more scales in the center and fewer toward the cap edge. The surface is dry, not slimy.

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.

Gilled hymenophore: gills free (not attached to the stem), crowded. When young they are pink (a characteristic feature of the genus Agaricus, unlike the white gills of amanitas), and with age they become chocolate-brown to dark brown. Spore print dark brown.

Stem 5-10 cm tall, 0.8-1.5 cm thick, cylindrical, slightly thickened at the base. Color white to cream. A white membranous ring in the upper part, distinct when young; in older mushrooms it may slip down or dry out. Above the ring the stem is smooth, below it has fine lengthwise fibers.

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.

Flesh firm, white; when cut it slowly turns pinkish to brownish, especially in the lower stem. This is the classic protective feature of the genus Agaricus against Amanita. In amanitas the flesh does not change color. Pleasant mushroomy smell with an almond note.

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.

Pleasant and mushroomy, with a subtle almond-anise note, typical of many Agaricus species. It does not smell of ink, medicine or carbolic (if it does, it is the yellow stainer: do not eat it).
