Not poisonous, but inedible: so bitter that a single mushroom spoils a whole meal.

Recognise it safely – what matters

  1. Tubes turn pink (porcini: white → yellow → olive green)
  2. Dark, coarse network on the stem (porcini: fine, pale network)
  3. Pink tint under the cap even in young mushrooms

Risk of confusion

Porcini Mushroom Edible species The most common porcini lookalike. Check the tubes (pink instead of yellow-green) and the coarse, dark stem network. Rough-stemmed Bolete Edible species Birch boletes have dark scales on the stem instead of a network and grow near birches.

Never identify mushrooms by pictures or an app alone. When in doubt, ask a mushroom expert – and only pick what you know for sure.
