When is the best time to find Chanterelle in Hauts-de-Seine?
Mushroom season in Hauts-de-Seine, France is building right now, with chanterelle sitting at 16% today. The typical season runs June to October, and we’re in July now
Fruits in warm, humid weather a week or two after steady summer rain, typically when soil stays moist and temperatures sit around 15 to 20 C. A wet spell breaking a dry period often brings a flush.
Often shares ground with porcini and other boletes in the same oak and birch woods, and you may find hedgehog mushrooms nearby in late summer. Look for ground patches where moss and blaeberry or bilberry grow on acidic soil.
Keep fresh in a paper bag in the fridge for up to a week, brushing off dirt rather than washing them wet. They do not dry as well as many mushrooms, so for longer keeping cook them first then freeze, or preserve in oil or by pickling.
The main dangerous lookalike is the Jack o’lantern (Omphalotus illudens, and the European Omphalotus olearius), which is toxic and causes severe sickness; it grows in clumps on wood or stumps and has true sharp gills rather than blunt forked ridges. The false chanterelle (Hygrophoropsis aurantiaca) is also confused with it but has thinner, true gills and a more orange colour, and is best avoided.
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.
