Identification

Dense wood clusters; brown speckled caps; stems with a ring; white spore print.

Edibility — conditional

Edible cooked — undercooked honey fungus causes gastrointestinal illness. Caps are best; stems get woody.

The deadly double

  • Bordered galerina: smaller, fragile ring, rusty spores — amatoxins.
  • When in doubt: a white spore print is honey fungus; rusty is danger.
