The oyster name covers a group of related mushrooms with members for nearly every season. Alongside the cold-loving Pleurotus ostreatus, the pale or summer oyster Pleurotus pulmonarius fruits from late spring through summer on the same kinds of dead hardwood, so a warm-season find here is genuine and the forecast reflects this wider group.
Fan-shaped or oyster-shell cap, usually 5 to 15 cm across, in shades of grey, brown, blue-grey or cream. White decurrent gills run down a short stubby off-centre stem or attach almost directly to the wood, and the flesh has a mild pleasant smell.
Keep fresh caps in a paper bag in the fridge for up to about five days, avoiding sealed plastic which makes them slimy. They dry well in a dehydrator or warm airy spot, and cooked oysters can be frozen; raw freezing tends to make them watery.
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.
East Sussex is a county of contrasts, where the chalk ridge of the South Downs runs east to the dramatic cliffs of Beachy Head and the Seven Sisters near Eastbourne. Inland lies the High Weald, a patchwork of sandstone ridges, deep wooded ghylls and small clay valleys, with the low marshes of the Pevensey Levels along the coast. The High Weald is one of the most densely wooded parts of England, full of ancient woodland dominated by oak, beech, hornbeam, birch and sweet chestnut, while Ashdown Forest adds open heath and pine on its sandy ridges. Mushrooms thrive in these old broadleaf woods, along damp ghyll streams and in the grassy margins of the chalk downland.
The county has a mild, damp maritime climate, with relatively warm autumns and steady rain rolling in off the Channel. These soft, humid conditions keep the woodland floor moist well into the season, which suits fungi. Foragers in East Sussex can expect a long, productive autumn across the ancient Wealden woods, the chestnut coppices and the downland edges, with chalk and acid-sandstone soils giving very different species side by side. Much of the High Weald is privately owned, so it is worth seeking permission and knowing where public access applies.
