Is it Porcini season in Marne right now?
Mushroom season in Marne, France is building right now, with porcini sitting at 28% today. The typical season runs August to November, and we’re in October now
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.
Brown bun shaped cap, often greasy when damp. The underside has a sponge of pores, white at first then turning yellowish to olive, never red. The thick bulbous stem is pale with a fine raised white network near the top, and the flesh is white and does not change colour when cut. Smell is pleasant and nutty.
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.
Marne lies in north-eastern France, crossed by the river that names it. Its core is the Champagne crayeuse, a dry, open chalk plain, edged to the west by the wooded plateau of the Montagne de Reims and the vineyard slopes of the Côte des Blancs. Eastward spread the damper clay lowlands of the Champagne humide and the Argonne ridge. The Montagne de Reims plateau carries deep oak, beech and hornbeam woods, home to the famous twisted dwarf beeches, the Faux de Verzy. On the thin chalk soils, Scots and Austrian pine were widely planted, while the eastern Argonne rises on siliceous gaize under oak and beech. This mix of calcareous and acid ground yields varied fungal habitats.
Marne has a semi-continental climate, a transition between the oceanic west and continental east, with cold winters and warm summers. Rainfall is moderate, around 600 to 700 mm, fairly even through the year. Autumn brings damp, cooling air that, after summer storms, triggers the main mushroom flush from September into November. Foraging splits by soil: the acid woods of the Montagne de Reims and Argonne give ceps (cèpes), chanterelles and black trumpets under oak and beech, while the chalk pine plantations offer saffron milkcaps and Suillus boletes. Damp Champagne humide woodland and lake margins add further finds. Autumn after rain is the prime window.
