Is it Oyster season in Pyrénées-Atlantiques right now?

Oyster usually come up in Pyrénées-Atlantiques from January to December, and right now they’re at 6% and just starting.

It is one of the few choice mushrooms that fruits in cool weather, often after the first autumn frosts and through mild winter spells when temperatures sit around 5 to 15 C. A drop in temperature following damp conditions is the main trigger, so look in the days after cold rain rather than after summer heat.

On the same dead hardwood you may find other wood-rotters such as turkey tail, jelly ear and velvet shank, which also fruit in the cold months. The similar branched oyster and pale oyster grow in comparable spots, and on conifers you should expect look-alikes rather than true oysters.

Look for overlapping shelf-like clusters on tree trunks and logs, often high up, and check the underside for decurrent gills that run down a short off-centre stem. Pick young specimens that are still firm and pale, as old ones turn tough, leathery and prone to insect larvae.

Can be confused with the angel’s wings (Pleurocybella porrigens), which is white, thinner and grows on conifer wood and has caused poisoning, so check the substrate and colour. The mild bitter oysterling (Panellus) and lung oyster are smaller and less fleshy but not dangerous.

Pyrénées-Atlantiques fills France’s far southwestern corner, rising from the Bay of Biscay across the green hills of the Basque Country and Béarn to the high Pyrenean crests along the Spanish border. The Pic du Midi d’Ossau towers over deep valleys – Aspe, Ossau, Barétous – carved by the gaves and cut with limestone gorges. Beech rules the mid-mountains, where the vast Iraty forest, among Europe’s largest beech woods, spills across the frontier before giving way to beech-fir stands higher up. The lower hills mix pedunculate oak, Pyrenean oak and chestnut. This damp, mossy mosaic on limestone and acid soils makes prime mycorrhizal ground.

The climate is markedly oceanic and among the wettest in France, with abundant year-round rain that the mountains wring even higher. Winters stay mild near the coast, summers turn warm and humid, and moist Atlantic air keeps the woods sodden. Such steady humidity yields a long, reliable autumn mushroom season. This is classic cep country: the cèpe de Bordeaux (porcini) is a regional emblem, gathered under beech and oak from late summer into autumn. Chanterelles brighten mossy slopes, black trumpets hide in the leaf litter, and the oronge (Caesar’s amanita) appears in warm oak woods. Damp valleys and beech forests reward the patient forager.
