Season

Indicative period: July to November.

Habitat

Mixed and broadleaf woodland, particularly beneath beeches, sometimes in wooded parks.

Method

Check several visible features before retaining a species name.

Three features to check on the specimen.

  1. Cap

    Convex to flattened, dark brown to reddish-brown, generally with few cracks.

  2. Pores

    Yellow, then olive-yellow pores, large and angular, turning blue-green when pressed.

  3. Stem and flesh

    Yellow stem finely dotted or streaked with red, often red near the base, without a network. Yellow flesh, sometimes wine-red at the base, slowly turning blue, especially above the tubes.

Examine the specimen in this order.

  • Examine the underside and the stem all the way to its base.
  • Compare the flesh reaction only on a section already needed for examination.
  • Keep the host tree and habitat as supporting evidence.

Features incompatible with this species.

  • Xerocomellus chrysenteron, with a cracked cap revealing pink.
  • Hortiboletus rubellus, with a bright red cap.
  • Imleria badia, with a brown stem lacking red tones.
