Look-Alikes
Species to rule out before picking. Each is tagged with its own edibility.
Leccinum aurantiacum (Red-Scaber Stalk)
EdibleEDIBLE. Orange cap. Both safe.
Leccinum insigne (Aspen Bolete)
EdibleEDIBLE under aspen if thoroughly cooked. Orange-capped Leccinum occasionally upset some people, especially when undercooked.
Identification Tips
- ✓Black scabers on a white stem = Leccinum genus
- ✓Cook thoroughly — raw Leccinum can cause GI upset
- ✓Host tree matters: birch = L. scabrum
