  • Spore Print: Dark brown to black, powdery

  • Habitat: Coniferous and mixed forests, often in sandy or acidic soils

  • Growth Pattern: Hypogeous (underground); usually solitary or scattered in groups

  • Seasonality: Summer–autumn fruiting, may persist into winter

Basics
  • Fruiting Body: Subterranean, nearly spherical, typically 1–4 cm across. Peridium (outer rind) thick, yellowish to reddish-brown, rough or granular, sometimes cracked with age.

  • Interior (Gleba): Pale whitish when young, becoming dark brown to black and powdery at maturity, with faint marbling from sterile veins.

  • Odor: Mild and earthy when young; stronger and sometimes unpleasant in older specimens.

  • Texture: Firm with a tough rind, crumbly spore mass when mature.

  • Spore Print: Dark brown to black (powdery at maturity)

  • Habitat: Mycorrhizal with conifers (pine, spruce, fir) in Europe, North America, and Asia

  • Season: Summer to autumn; fruiting bodies often persist underground into winter

  • Edibility: Considered inedible for humans; lacks culinary value and may cause mild digestive upset.

  • Ecologically important as a wildlife food source — consumed by deer, wild boar, squirrels, and small mammals.

  • Key role in spore dispersal via mammal digestion and deposition.
