How are Oyster doing in Conwy this September?
Oyster usually come up in Conwy from January to December, and right now they’re at 19% and building.
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.
Tear into strips and pan-fry hard in butter or oil until the edges crisp and brown, then season with salt and a little garlic. They also work well in stir-fries, folded through risotto or pasta, or added to soups and stews where their firm texture holds up. Cook them thoroughly as they are not eaten raw.
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.
Conwy runs from the North Wales coast around Llandudno and Colwyn Bay up the broad Conwy Valley to the rugged Carneddau mountains of Eryri (Snowdonia). It is a county of sharp contrasts, where tidal estuary and farmland give way to high, windswept moorland and bare summits. Sessile oak woods cling to the valley sides, while the conifer plantations of Gwydir Forest above Betws-y-Coed dominate the uplands. Mushrooms turn up among the oak, birch and beech of the damp valley floor, on mossy banks, and along the rides and clearings of the pine forests.
The climate is mild and distinctly wet, with the Carneddau wringing heavy rain out of Atlantic weather while the coast stays milder and drier. This near-constant moisture keeps the woods humid well into autumn, ideal for fungi. Expect a long, productive autumn season, richest in the oak and birch woodland of the Conwy Valley and the conifer plantations around Gwydir. The high open moors of the Carneddau hold their own grassland species, so it pays to range from estuary to mountain.
