When will Chanterelle appear in Yvelines?

Chanterelle usually come up in Yvelines from June to October, and right now they’re at 15% and building.

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.

Egg-yolk to golden yellow throughout, with a cap that is convex when young and becomes wavy and funnel-shaped with an inrolled edge. Instead of true gills it has blunt, forked, vein-like ridges that run down the stem, and the flesh is firm with a smell of apricots.

Look low to the ground for the gentle apricot smell and the egg-yolk colour, and check that the underside has blunt forking ridges running down the stem rather than true thin gills. Cut or twist them carefully and leave small ones to grow, since patches return to the same spot year after year. Always be certain of identification and avoid the false chanterelle and the toxic orange jack-o-lantern, which has true gills and grows in clumps on wood.

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.

Yvelines lies west of Paris in the Paris Basin, a landscape of gently rolling limestone and sandy plateaus incised by river valleys. The Seine winds through in broad meanders around Mantes and the Meulan hills, fed by smaller rivers such as the Mauldre and the Vaucouleurs. Between them stretch the plateaus of the Hurepoix and the Mantois and the plaine de Versailles. Woodland is abundant, crowned by the vast Forêt de Rambouillet, one of the largest massifs in Île-de-France, alongside the forests of Marly and Saint-Germain-en-Laye. Sessile oak and beech dominate, mixed with Scots pine, sweet chestnut and birch on sandy, acidic soils dotted with ponds and heath – ideal ground for mycorrhizal fungi.

The climate is temperate oceanic with a slight continental edge, bringing mild, damp autumns and annual rainfall around 650-700 mm. Warm late-summer rains followed by cool, humid September nights trigger the main flush, which runs from September into November. Spring dampness can also bring morels. Foragers work the oak-and-pine stands of Rambouillet and Marly for cèpes and girolles, with pieds-de-mouton and trompettes-de-la-mort in the leaf litter. Sandy clearings and heathy edges yield boletes, while grassy rides and pastures produce parasols (coulemelles) and russulas in a good autumn.
