Boletus reticulatus
The summer cep is a large bolete that appears in summer under oaks. Its velvety brown cap can reach 30 cm and often cracks into a net-like pattern when dry. The swollen stem carries a strongly marked net pattern.
Lives in deciduous forests in partnership with oaks, appearing after hot and humid weather from early summer to the end of autumn.
Found in woods throughout Europe, especially common in southern and western France and the Italian Apennines; also recorded in Ukraine and Russia.
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.
Its old name Boletus aestivalis comes from the Latin for 'of summer'.
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).
