Boletus edulis
The penny bun is a large bolete whose bun-like brown cap can reach 30 cm across. Instead of gills it has tubes and pores, whitish when young and greenish-yellow later. The stout stem is partly covered with a fine, pale, net-like pattern.
Grows singly or in small groups in deciduous and coniferous forests, with pine, spruce, fir, oak, beech and chestnut, forming partnerships with tree roots.
Widespread in the Northern Hemisphere across Eurasia and North America; it does not occur naturally in the Southern Hemisphere but has been introduced there.
Identification suggestions (from the community or from AI) and the information here may be wrong; this app never confirms that anything is safe to eat. Do not consume wild plants, mushrooms or seafood without expert confirmation. Nothing here is medical advice.
Large penny buns are often full of fly maggots, so the biggest ones are frequently riddled with tunnels.
Never eat a wild mushroom without showing it to an expert
No mushroom should be picked for eating based on this app or a photo. Deadly species look very like the ones foragers look for, and symptoms start hours later. If you suspect poisoning, call your local poison centre or emergency number right away (in Türkiye: 114).

Fine pale net pattern on the upper part of a stout, swollen stem
Flesh stays white when cut, no blueing, no red on stem or pores — unlike the red stem and blueing flesh of Satan's bolete
Not known to be poisonous — still never eat it
