The Devil’s Bolete (Rubroboletus satanas) – The Demon in Mushroom Form

🌲 Introduction

The name alone should raise alarm: the Devil’s Bolete (Rubroboletus satanas). With its massive body, thick stem, and striking colors, this mushroom commands attention in the forest. But it is no friend to foragers—it is poisonous and capable of causing severe illness. Some call it the “Devil among boletes,” and for good reason.

🔎 Identification Features

The Devil’s Bolete is one of the largest and most striking bolete species in Europe.

• Cap: 4–12 inches wide, whitish to gray, velvety, often broadly convex.

• Pores: yellow when young, later turning bright red to blood red; bruise blue when pressed.

• Stem: thick, club-shaped, yellowish at the base, vivid red in the middle, covered with a fine net-like pattern.

• Flesh: whitish, slowly turning blue when cut.

• Odor: unpleasant, sweetish and putrid, especially in older specimens.

👉 Can be confused with edible boletes, but its vivid red pores and foul smell are strong warning signs.

☠️ Toxicity

The Devil’s Bolete is poisonous, causing violent gastrointestinal symptoms. Even small amounts can lead to:

• Nausea and vomiting

• Severe abdominal pain

• Diarrhea

👉 While it is not as deadly as the Death Cap or Deadly Webcap, its effects are intense, painful, and long-lasting. In some regions, folklore claims it can be eaten after long boiling—but this is extremely dangerous and strongly discouraged.

🌟 Special Characteristics

• Impressive size and color: its massive cap and vivid red pores make it one of the most eye-catching mushrooms in the forest.

• Myth and name: nicknamed “Satan’s mushroom” for centuries, seen as an omen of bad luck.

• Habitat: thrives in warmer European regions, particularly in calcareous soils under oak and beech trees.
