Are Oyster mushroom out in Argyll and Bute yet?
Mushroom season in Argyll and Bute, Scotland is just starting right now, with oyster mushroom sitting at 7% today. The typical season runs January to December, and we’re in July 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.
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.
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 (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.
Argyll and Bute is a deeply indented stretch of Scotland’s west coast, where sea lochs like Loch Fyne and Loch Etive cut between rugged hills, peninsulas such as Kintyre and Cowal, and a scatter of islands including Mull, Islay and Bute. Rocky shorelines, heather moorland and steep glens dominate, with few areas of flat ground. Much of the region carries commercial Sitka spruce plantations, but there are also pockets of native oak, birch and hazel, including the lush Atlantic oakwoods around Loch Sunart and the Argyll rainforest. Mushrooms turn up along forest tracks and clearings, in mossy native woods and on the mosaic of moor and rough grazing.
This is one of the wettest, mildest parts of Britain, washed by the Atlantic and warmed by the Gulf Stream, with heavy rainfall spread through the year and high humidity. These damp, frost-poor conditions keep the ground moist and suit fungi well, supporting the temperate rainforest character of the western glens. Foragers can expect a long, productive autumn season, with chanterelles and ceps among the conifers and a rich variety of fungi in the old oakwoods. The terrain is wet and often remote, so good boots and an eye on the tides and weather pay off.
