Oyster mushroom in Devon, England: live forecast and 14-day outlook
Oyster mushroom usually come up in Devon from January to December, and right now they’re at 23% 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.
Pleurotus ostreatus is a carnivorous fungus that secretes toxins to paralyse and digest tiny nematode worms, supplementing the nitrogen it gets from rotting wood.
A good edible with a mild savoury flavour and firm texture that holds up well to frying, roasting and stir-frying. Cook thoroughly and discard tough stem bases.
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.
Devon spans two upland national parks – the granite tors and high moorland of Dartmoor and the heather uplands of Exmoor – that fall away into rolling pastoral farmland and deep, wooded river valleys known as combes. The county is unusual in having two coasts: a rugged Atlantic shoreline in the north and the milder, sheltered estuaries of the south. The richest fungal ground lies in Devon’s Atlantic oakwoods, including the moss-draped temperate rainforest fragments on Dartmoor such as Wistman’s Wood, alongside mixed broadleaf valley woodland of oak, beech, hazel, ash and birch. Damp combes, old hedge banks and grazed pastures all add productive habitat.
Devon has a mild, oceanic climate with abundant rainfall, especially over Dartmoor where the high ground wrings moisture from the Atlantic air. The frequent mist, humidity and long, gentle autumns keep the woodland floor reliably damp – ideal conditions for fungi. Expect a long and generous season in Devon, from summer chanterelles and ceps in the oakwoods to a wide autumn flush of boletes, hedgehog fungus and field mushrooms in the old pastures. Much of Dartmoor and Exmoor is open access, though large stretches are protected, so forage lightly and stick to common, well-identified species.
