When will Porcini appear in Hauts-de-Seine?

Mushroom season in Hauts-de-Seine, France is looking good right now, with porcini sitting at 47% today. The typical season runs August to November, and we’re in October now

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.

Check around the bases of host trees and along sunlit forest edges, returning to productive spots a few days apart through the flush. Cut or twist the stem cleanly, slice each cap to check for maggots, and take only young specimens with white firm flesh.

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.

Hauts-de-Seine wraps around the western edge of Paris, a small, densely built département shaped by the looping meanders of the Seine. Its land is gently undulating: a low alluvial valley floor near 30m rises to wooded plateaus and buttes around Meudon and Ville-d’Avray, close to 180m. Despite the urban sprawl, wooded plateaus survive as the Forêt de Meudon, Forêt de Fausses-Reposes and Bois de Clamart, capped by acidic Fontainebleau sands and clay-with-flints. Sessile oak, sweet chestnut, hornbeam and birch dominate, and the warm, acid, leaf-littered soil makes classic ground for boletes and chanterelles.

The climate is temperate oceanic, softened further by the surrounding city: mild winters, warm humid summers and modest rainfall of around 600-650mm spread evenly through the year. Autumn is the reliable flush, when September and October rains meet soil still warm from summer; damp springs can bring morels. Foraging here is peri-urban and pressured, worked in the leafy folds of Meudon, Clamart and Fausses-Reposes rather than deep wildwood. Under oak and chestnut come ceps, bay boletes, girolles, russulas and amanitas, with parasols and blewits on grassy edges; pick knowingly, for Paris is close.
