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.
Late summer into autumn, roughly August to November in Britain and Ireland.
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.
Ardèche sits on the eastern flank of the Massif Central, dropping from the granite plateaux and volcanic summits of the Ardèche and Tanargue mountains toward the Rhône valley. Deep limestone gorges cut by the Ardèche river, the wooded Cévennes foothills and high open plateaux give it sharp contrasts of altitude and rock. Sweet chestnut is the emblematic tree, blanketing the mid-slopes in orchards and wild groves, alongside sessile oak, beech and Scots pine. Higher ground carries spruce, fir and beech, while the southern limestone hills hold downy oak and holm oak. This mix of acidic chestnut soils and calcareous garrigue makes exceptionally varied fungi ground.
The climate ranges from humid mountain conditions in the west to a warm Mediterranean influence in the south and Rhône lowlands. Violent autumn rain storms, the Cévenol episodes, soak the ground in September and October and trigger the main flush. Warm valleys can extend the season, while high plateaux see snow and a short cold summer. Chestnut and oak woods yield ceps and porcini, girolles and chanterelles, along with the prized cèpe de Bordeaux after autumn storms. Limestone garrigue offers black trumpets, blewits and truffle-country oaks in the south, while pine and fir belts hold saffron milkcaps. Autumn after Cévenol rains is the peak.
