How are Porcini doing in Ardennes this September?
Porcini usually come up in Ardennes from August to November, and right now they’re at 71% and running strong.
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.
Late summer into autumn, roughly August to November in Britain and Ireland.
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.
The Ardennes departement rises in the north into the forested Ardenne massif, a schist plateau near 500 metres cut by the deep, winding gorges of the Meuse and Semois. Southward the land softens into the chalk plains of Champagne and the wooded Argonne ridge, with the damp Thierache to the west. Around a third of the departement is wooded. The acidic massif carries dense oak and beech alongside plantations of Norway spruce and Douglas fir, while the Argonne ridge holds oak, beech and hornbeam on damp gaize soils. These cool, acid, humus-rich woods are prime fungal ground.
The climate is semi-continental with oceanic moisture, coolest and wettest over the upland massif, where mist and 1,000-plus millimetres of rain are common. Cold winters and mild, damp summers keep the leaf litter reliably humid, driving strong mushroom flushes from September into November. Foragers work the acid oak and beech stands for ceps and golden chanterelles, and the spruce plantations for bay boletes and slippery jacks. Beech hollows yield black trompettes de la mort, while the perpetually damp valleys of the Meuse and Argonne stay productive deep into autumn.
