Fungus
Aspen Bolete
Leccinum insigneAlso known as Aspen Scaber-stalk
Aspen bolete forms an orange to red-brown cap above a pale stalk covered in dark rough scabers. Pores rather than gills line the cap underside, and the underground mycelium exchanges nutrients with aspen roots.

Interaction riskHigh
- Low
- Moderate
- High
- Very high
- Why interaction risk is high
- Bolete look-alikes are dangerous; do not eat or ingest wild fungi, especially raw specimens.
- Why it is dangerous
- Raw specimens can cause poisoning, and similar reddish-capped boletes may be hazardous when misidentified.
- How to recognize a risky encounter
- An orange to red-brown cap, pale pores, dark stem scabers, and nearby aspen are key clues.
- What to do
- Never consume or taste a wild mushroom; keep children and pets away from collected specimens.
Responsible observation
- Underside: Confirm pores rather than gills without breaking the cap.
- Stalk: Observe dark scabers and nearby aspen while leaving the fungus rooted.
