When will Porcini appear in Hautes-Pyrénées?
Porcini usually come up in Hautes-Pyrénées from August to November, and right now they’re at 49% 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.
Grows in mycorrhizal partnership with trees, especially under pine, spruce, birch, beech and oak, on well drained soil. Found in conifer and broadleaf woodland and along woodland edges and tracks.
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.
Hautes-Pyrénées climbs from the Bigorre plain and the Plateau de Lannemezan to a wall of peaks on the Spanish border, crowned by Vignemale (3,298 m) and the Pic du Midi de Bigorre. Glacier-carved valleys – Aure, Louron, Argelès, Campan – and the great Cirque de Gavarnie are drained by the young Adour and its gaves. Mid-slopes are cloaked in beech and beech-fir forest, silver fir mixing with the hêtraie between roughly 800 and 1,700 m, while oak and chestnut hold the warmer piedmont and hardy mountain pine climbs toward the Néouvielle lakes. This damp, humus-rich mountain woodland is classic cep ground.
Sitting in the western Pyrenees, the departement catches the full brunt of Atlantic westerlies, making it markedly wetter than the eastern ranges. Valleys stay mild while altitude brings cold, snowy winters; warm, thundery late summers followed by soaking autumn rains trigger the main mushroom flushes. Foragers work the beech-fir slopes and pasture edges for cèpes (Boletus edulis and pinophilus), golden girolles and black trompettes de la mort. Pied-de-mouton and, under the pines, saffron milk-caps round out baskets, with the season climbing the valleys from late summer high into autumn.
