It is one of the few choice mushrooms that fruits in cool weather, often after the first autumn frosts and through mild winter spells when temperatures sit around 5 to 15 C. A drop in temperature following damp conditions is the main trigger, so look in the days after cold rain rather than after summer heat.
Pleurotus ostreatus is a carnivorous fungus that secretes toxins to paralyse and digest tiny nematode worms, supplementing the nitrogen it gets from rotting wood.
A good edible with a mild savoury flavour and firm texture that holds up well to frying, roasting and stir-frying. Cook thoroughly and discard tough stem bases.
Can be confused with the angel’s wings (Pleurocybella porrigens), which is white, thinner and grows on conifer wood and has caused poisoning, so check the substrate and colour. The mild bitter oysterling (Panellus) and lung oyster are smaller and less fleshy but not dangerous.
Hertfordshire is a gently rolling lowland county just north of London, where chalk uplands of the Chiltern Hills rise in the north-west and give way to clay-capped plateaux and shallow river valleys carved by chalk streams like the Ver, Mimram and Gade. There is no coast here; the character is one of farmland, hedgerows and pockets of ancient woodland threaded through commuter towns. The Chiltern slopes are famous for their beechwoods, while the heavier London Clay and boulder-clay soils to the south and east carry oak, ash, hornbeam and hazel coppice. Mushrooms turn up in this leaf litter and on old stumps, along woodland rides, and on the unimproved grassland of commons and chalk downland.
The climate is mild and temperate with year-round rainfall, though as one of the drier, more sheltered parts of England it sees less rain than the west. Damp, mild autumns after late-summer showers give the most reliable flushes. Expect classic southern English lowland foraging: penny buns and other boletes under beech and oak, chanterelles on mossy banks, field and parasol mushrooms in old pasture, and plenty of inkcaps and waxcaps in autumn. Much of the woodland sits on protected commons or private estates, so check access and pick modestly.
