Hazel Bolete

Leccinellum pseudoscabrum · family Boletaceae

Description

The hazel bolete is a pored mushroom of the bolete family, related to the birch bolete. It grows only under hornbeams, and its flesh turns from dirty pink to blackish when damaged.

In Poland it is included in the list of mushrooms approved for sale under the name koźlarz grabowy. Before collecting you must be sure of the species; it can be confused with the birch bolete, which grows under birches.

If you are not sure of the species, do not pick it and do not eat it.

What can it be confused with?

  • Leccinum scabrum (birch bolete) — Grows under birches, not under hornbeams; the flesh does not change colour when damaged, whereas in the hazel bolete it turns from dirty pink to blackish.

Never rely on a single feature. If you are not sure — do not pick it; show the mushroom to a qualified mushroom expert.
