Boletus Satanas

Hans Walty (Swiss, 1868–1948)

Hans Walty’s illustration of Boletus satanas, or Satan’s Bolete, is a detailed study of one of Europe’s most striking and toxic mushrooms. Found primarily in warm, temperate regions of southern and central Europe, Boletus satanas thrives in calcareous soils, often growing in symbiosis with oak, beech, and chestnut trees. It is most commonly spotted in forests and woodland clearings, particularly in summer and early autumn.

The species is notable for its thick, swollen stem, often tinged with red, and its pale cap, which can develop a cracked, weathered appearance. The striking red pores beneath the cap turn blue when bruised—an identifying feature that also signals its toxicity. Though visually similar to edible boletes, Boletus satanas is poisonous and can cause severe gastrointestinal distress if consumed.

Walty’s illustration captures these defining characteristics with scientific precision, aligning with early 20th-century botanical and mycological documentation efforts. His work likely contributed to field guides and scientific studies aimed at cataloging European fungi, ensuring both their beauty and their dangers were accurately recorded. This piece is part of a broader tradition of natural history illustration, where art and science intersect to preserve knowledge of the natural world.
