How are Porcini doing in Ille-et-Vilaine this October?
Porcini usually come up in Ille-et-Vilaine from August to November, and right now they’re at 40% and looking good.
Fruits after warm, humid spells when soil temperatures sit in the mid teens Celsius and a good soaking rain follows a warm period. A typical trigger is heavy rain after several warm days, with flushes appearing roughly one to two weeks later.
Brown bun shaped cap, often greasy when damp. The underside has a sponge of pores, white at first then turning yellowish to olive, never red. The thick bulbous stem is pale with a fine raised white network near the top, and the flesh is white and does not change colour when cut. Smell is pleasant and nutty.
One of the finest edible mushrooms, with a deep savoury nutty flavour. Excellent fresh in risotto, sauces and fried in butter, and it dries very well to concentrate the flavour for stocks and soups.
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.
Ille-et-Vilaine lies in eastern Brittany on the Armorican Massif, a country of low rolling relief, bocage hedgerows and small fields. The Ille and Vilaine rivers that give it its name meet at Rennes, while the north dips to the coastal marshes of the Baie du Mont-Saint-Michel near Cancale and Saint-Malo. Though Brittany is lightly wooded, the departement holds fine oak and beech massifs – the forests of Rennes, Liffré, Villecartier and above all Paimpont, the legendary Brocéliande. Scots pine, birch and sweet chestnut grow on its acidic Armorican soils, and the dense bocage hedgerows add rich mycorrhizal edges.
The climate is mild and oceanic, tempered by Atlantic westerlies, with rain spread across the year and high humidity. Winters stay soft and summers cool, though Rennes runs a touch drier than the coast. Warm, wet autumns from September into November set the main flushes, and damp late-summer spells can start them early. Foraging favours the oak-beech forests, pine plantations and chestnut groves, with productive edges along the bocage and the heathy clearings of Paimpont. Foragers find cèpes (Boletus edulis), girolles, black trumpets and pieds-de-mouton, with parasols in grassy verges – the acidic soils suiting chanterelles especially well.
