Porcini is really a small group of closely related boletes. The summer cep (Boletus reticulatus, also called Boletus aestivalis) fruits in warm broadleaf woodland from late spring into summer, well before the main autumn flush of Boletus edulis, so an early-season find is entirely natural. The forecast reflects this wider group.
Grows in mycorrhizal partnership with trees, especially under pine, spruce, birch, beech and oak, on well drained soil. Found in conifer and broadleaf woodland and along woodland edges and tracks.
Slice young firm caps thin and fry in butter with garlic and parsley, or add to risotto and pasta sauces. Older or wormy specimens are best dried and ground into a powder to deepen stocks, soups and gravies.
Can be confused with the bitter bolete (Tylopilus felleus), which has a darker net on the stem, pinkish pores when mature and a strongly bitter taste, and with red pored boletes. Avoid any bolete with red or orange pores or flesh that stains strongly blue, and taste a tiny piece of any doubtful bolete to detect bitterness.
Finistère forms the westernmost tip of Brittany, a granite peninsula thrust into the Atlantic with a deeply indented coast of cliffs, rias and abers. Inland rise the low, ancient ridges of the Monts d’Arrée and Montagnes Noires, cloaked in heath and peat bog, with a patchwork bocage of hedged fields between. Though Brittany is lightly wooded, Finistère holds fine oak and beech forests such as the Cranou and Huelgoat, the latter strewn with mossy granite boulders. Sessile oak, beech, chestnut and birch grow on damp, acidic granite soils, forming rich mycorrhizal ground, while hedgerows and conifer plantations add further habitat.
The climate is thoroughly oceanic – mild, humid and wet, driven by Atlantic westerlies. Rain falls year-round and coastal frost is rare, so autumns stay long, damp and gentle. These mild, moist conditions extend the fungal season well into late autumn, with flushes possible from late summer onward. Foragers work the acidic oak and beech woods of the interior for girolles (chanterelles) and cèpes, with birch boletes on heathy margins and trompettes de la mort in shaded beech litter. Bocage hedgerows, mossy Huelgoat boulders and damp valley floors all reward searching through a long, mild autumn.
