When will Porcini appear in Greater London?
Porcini usually come up in Greater London from August to November, and right now they’re at 46% and looking good.
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.
Greater London occupies the broad, low-lying floor of the Thames Basin, straddling the tidal River Thames and its tributaries like the Lea and Wandle. Beyond the built-up core, the land rises gently into wooded commons and green-belt fringes such as Hampstead Heath and the Epping ridge. Ancient woods and royal parks dominate the green spaces here, with oak, beech, birch and hornbeam, plus famous old pollards in Epping Forest and sweet chestnut on the heaths. Look for fungi among leaf litter under the trees, on old hardwood logs, and in the unimproved grassland of commons like Richmond Park and Wimbledon Common, where waxcaps appear.
London has a mild, temperate maritime climate, slightly warmer and drier than the surrounding countryside thanks to the urban heat island. Rainfall is moderate but spread through the year, and damp, mild autumns reliably trigger fungal flushes. Foraging in London means working the large parks, heaths and ancient commons rather than wild country, so expect competition and local picking restrictions in many royal parks. Autumn brings a good variety in the better woodlands, but always check the rules for each site before collecting.
