How are Porcini doing in Morbihan this October?

Porcini usually come up in Morbihan from August to November, and right now they’re at 39% and building.

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.

Forms mycorrhizal partnerships with conifers (spruce, pine) and broadleaves (oak, beech, birch), so look at the edges and clearings of these woods. It favours mossy banks, well drained acidic soils and the grassy verges of woodland paths rather than dense leaf litter.

One of the finest edible mushrooms, with a deep savoury nutty flavour. Excellent fresh in risotto, sauces and fried in butter, and it dries very well to concentrate the flavour for stocks and soups.

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.

Morbihan lies in southern Brittany on the Atlantic, named for its ‘little sea’, the island-studded Gulf of Morbihan. Its indented coast takes in the Quiberon peninsula and Belle-Île, while inland a low bocage of granite and schist rises to the wooded ridge of the Landes de Lanvaux, drained by the Blavet, Oust and Vilaine. Oak and beech dominate the great inland forests, above all Brocéliande (Paimpont) and Camors, mixed with Scots and maritime pine, chestnut and birch on the heaths. The acidic Armorican soils, damp hollows and mossy leaf litter under both broadleaf and conifer make rich, varied ground for fungi.

The climate is mild and oceanic, with wet Atlantic autumns, cool summers and frosts rare near the coast, where the Gulf keeps its own gentler microclimate. Steady humidity and long, damp September-to-November spells give a generous main season, often extended by soft, frost-free early winters inland. Autumn foraging centres on the oak-beech woods and pine-clad heaths of Lanvaux and Brocéliande. Cèpes and pine boletes, golden chanterelles, trumpets of the dead, hedgehog mushrooms and saffron milkcaps under pine, plus russulas and amanitas, reward walkers along the bocage edges and damp valley floors.
