Lycoperdon umbrinum - Mushroom pearly or cone-shaped, in the middle with a blunted umbo; 20 to 50 mm high, 20-50 mm wide; upper part spherical, bulbous; bottom short narrowed, advised. At the base of well-developed mycelial cords (rhizomorphs). Outer sheath: exoperidium with thick, thin, fairly durable, curled spines (height 1 mm), dark brown or black, single or grouped, pyramid shape. Surface between the spines smooth, brown; after ending, endoperidium is discovered. Inner cover: endoperidium smooth, shiny, whitish, later brown-yellow, brownish. After ripening at the top, it breaks with a small hole giving the spores an outlet.

The fruiting body of the young subsoil is soft, elastic, whitish, gray-brown, gray-violet.
Aqueous, soft, olive-brown soil, spore mass, fibrous.
Fungus in the lower, capstic, porous, gray- and olive-brown. Mushroom smell, delicate flavor.

Occurrence: In various forests, more often in mountain spruce; on the earth; quite often, sometimes it grows en masse, for example on spruce felling. It grows from August to October.

Value: Edible mushroom, but only young specimens, when the fruiting body's interior is white, it can be eaten after removing the surface.
