How are Oyster doing in South Yorkshire this September?
Mushroom season in South Yorkshire, England is building right now, with oyster sitting at 17% today. The typical season runs January to December, and we’re in September now
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.
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.
South Yorkshire rises from the gritstone moorland of the Dark Peak in the west, where Peak District edges and high plateaus overlook Sheffield, and falls eastward through wooded river valleys and the old coalfield to the flat, low-lying farmland of the Humberhead Levels around Doncaster. Steep cloughs and valley sides hold ancient broadleaved woodland of oak, birch and beech, while the cleared coal-measure country is dotted with old hedgerows and replanted plantations; look for fungi in the leaf litter of these clough woods and along stream banks, with conifer stands on the higher ground favouring boletes.
The climate is cool and damp with a clear west-to-east gradient: the Pennine moors above Sheffield catch heavy rainfall and stay wet, while the eastern lowlands around the Don are drier and milder, giving the woods a long, reliably moist autumn season. Expect a rewarding mix within a short drive, from upland birch and pine for chanterelles and ceps to lowland oak and beech woods for a broad autumn flush; much of the best ground sits in accessible Peak District fringe woodland and former colliery plantations, so check access and stick to common, well-known species.
