When will Porcini appear in Oise?

Porcini usually come up in Oise 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.

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.

Oise lies in northern France within the old province of Picardy, a land of gently rolling chalk plateaus draped in wind-blown loam. The Oise and Thérain rivers carve broad valleys through open farmland, and large forest massifs break the plains. Sandy soils surface in the south near Chantilly and Ermenonville. Great state forests define Oise: Compiègne, Laigue, Halatte, Chantilly and Ermenonville. Oak, beech and hornbeam grow on the richer loams, while Scots pine and birch colonise the sandy soils of the south. The mix of deep leaf litter, mossy clearings and varied ground makes fertile mushroom country.

The climate is temperate and oceanic, with rain spread evenly through the year, around 700 mm, and no dry season. Summers stay mild and winters soft, while autumn turns damp and misty. These humid September-to-November spells trigger the main flush, with morels appearing in a warming spring. Autumn foraging centres on the big forests: ceps and other boletes push up under the oaks and beeches of Compiègne and Halatte, with golden chanterelles in the mossier stands. The sandy pinewoods around Ermenonville and Chantilly yield further boletes, while spring morels favour the poplar-lined river valleys.
