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.
