Is it Oyster season in Hampshire right now?
Oyster usually come up in Hampshire from January to December, and right now they’re at 41% and looking good.
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.
Mainly autumn to winter, and it can appear in mild spells through the colder months. Frost often triggers a flush.
Look for overlapping shelf-like clusters on tree trunks and logs, often high up, and check the underside for decurrent gills that run down a short off-centre stem. Pick young specimens that are still firm and pale, as old ones turn tough, leathery and prone to insect larvae.
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.
Hampshire runs from the rolling chalk downland of the South Downs in the east to the open heaths and ancient woods of the New Forest in the west, drained by clear chalk-stream valleys like the Test and Itchen. Its southern edge meets the Solent coast, with tidal mudflats and saltmarsh around Southampton Water and Portsmouth Harbour. The New Forest is the standout fungal hotspot, with old pollarded oak and beech, holly, birch and conifer plantations set among heathland and grazed lawns. On the chalk further east you find beech hangers and mixed broadleaf woods, where mushrooms favour the leaf litter, mossy banks and grazed pasture edges.
Hampshire has a mild, damp oceanic climate, with relatively warm autumns and steady rainfall coming off the Channel. These soft, humid conditions keep the woodland floor moist well into autumn, which suits a long fruiting season. Hampshire is one of England’s classic foraging counties, above all the New Forest, where a huge variety of species appears from late summer through autumn. Note that picking is restricted in the New Forest itself, so foragers should know the local rules and stick to permitted ground.
