Champignon White Button Mushroom (Agaricus bisporus) Mycelium Spawn Dried Seeds (25g) by Garden Pleasure

Description

The pileus or cap of the original wild species is a pale grey-brown in color, with broad, lat scales on a paler background and fading toward the margins. It is first hemispherical in shape before flattening out with maturity, and 5–10 centimetres (2–4 inches) in diameter. The narrow, crowded gills are free and initially, pink, then red-brown and finally a dark brown with a whitish edge from the cheilocystidia. The cylindrical stipe is up to 6 cm (2 1⁄3 in) tall by 1–2 cm wide and bears a thick and narrow ring, which may be streaked on the upper side. The firm flesh is white, although stains a pale pinkish-red on ruising. The spore print is dark brown. The spores are oval to round and measure approximately 4.5–5.5 μm × 5–7.5 μm, and the basidia usually two-spored, although two-tetrasporic varieties have been described from the Mojave Desert and the Mediterranean, with predominantly heterothallic and homothallic lifestyles, respectively. Gills: Free from the stem; close; short-gills frequent; pinkish to pink at first, becoming dark brown to nearly black. Stem: 2–7 cm long; 1–2.5 cm thick; more or less equal; bald or with small scales; white, often bruising reddish to brownish; with a thin ring that sometimes disappears in maturity. Flesh: White and firm; usually bruising and staining pinkish to reddish, then slowly brownish. Odor and Taste: Pleasant.
