When is the best time to find Oyster mushroom in Cumbria?
Oyster mushroom usually come up in Cumbria from January to December, and right now they’re at 8% and just starting.
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.
It grows on dead and dying hardwood, especially beech, poplar, willow, oak and aspen, appearing on standing trunks, fallen logs and stumps rather than on the ground. It favours damp deciduous and mixed woodland, parks and riverside trees where dead wood is plentiful.
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 (Pleurocybe 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.
Cumbria is England’s most mountainous county, dominated by the rugged Lake District fells with Scafell Pike and ribbon lakes like Windermere and Ullswater, fringed by the Pennines to the east and the Solway Firth and Irish Sea coast to the west. Between the high fells lie steep-sided dales, glacial valleys and patches of lowland pasture. The valleys hold ancient Atlantic oakwoods, famously in Borrowdale, mixed with birch, ash, hazel and holly, while the uplands carry large conifer plantations such as those in Grizedale and Thirlmere. Damp, mossy oakwoods, conifer edges and grazed pasture are the prime ground for fungi here.
This is one of the wettest parts of England, with a mild, oceanic climate and heavy rainfall trapped by the western fells, especially around Borrowdale and Wasdale. The persistent damp and humidity keep the ground reliably moist well into autumn. Cumbria is superb fungi country, rewarding walkers in its damp oakwoods, beneath conifers and on open fell grassland through a long autumn season. Bear in mind that much of the high ground sits within the Lake District National Park, so forage responsibly and respect access rules.
