Season

Indicative period: June to November.

Habitat

Broadleaf, mixed or conifer woodland, parks and wooded edges.

Method

Check several visible features before retaining a species name.

Three features to check on the specimen.

  1. Cap

    Convex to flattened, brown and irregularly cracked with pink-red flesh visible.

  2. Pores

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

  3. Stem and flesh

    Slender yellow stem with coral-red fibrils or streaks, especially near the base, without a network. Cream to yellow flesh, red beneath the cracked cap surface and turning blue in places when cut.

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 pruinatus, often uncracked with a finely frosted cap.
  • Hortiboletus rubellus, with a distinctly red cap.
  • Xerocomellus porosporus, with distinct microscopic features.
