How are Porcini doing in Haute-Saône this September?
Porcini usually come up in Haute-Saône from August to November, and right now they’re at 33% 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.
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.
Haute-Saône spreads across plains and low limestone plateaus in eastern France, crossed by the slow Saône and its tributary the Ognon. To the northeast the land climbs into the southern Vosges foothills, peaking at the Ballon de Servance, where the Plateau des Mille Étangs scatters hundreds of glacial ponds and peat bogs. Woodland covers over forty percent of the department, among the most forested in France. Oak, beech and hornbeam dominate the plateaus, while fir and spruce mix in on the higher Vosges slopes; damp alluvial woods line the Saône. This blend of acidic and limestone ground makes rich, varied fungi habitat.
The climate is semi-continental with an oceanic streak: cold, sometimes snowy winters and warm summers. Rain falls through the year and is heaviest over the Vosges foothills, where the Mille Étangs stays notably wet. Reliable late-summer and autumn humidity drives the main mushroom flush. Foragers work the oak-beech plateaus for cèpes and girolles, and the acidic Vosges woods for boletes and chanterelles. Damp hollows yield black trumpets in autumn, while spring brings morels to the alluvial thickets along the Saône and Ognon. This mixed ground rewards patient searching.
