Are Oyster out in Cardiff yet?
This week’s oyster forecast for Cardiff, Wales reads 13% and just starting.
It is one of the few choice mushrooms that fruits in cool weather, often after the first autumn frosts and through mild winter spells when temperatures sit around 5 to 15 C. A drop in temperature following damp conditions is the main trigger, so look in the days after cold rain rather than after summer heat.
On the same dead hardwood you may find other wood-rotters such as turkey tail, jelly ear and velvet shank, which also fruit in the cold months. The similar branched oyster and pale oyster grow in comparable spots, and on conifers you should expect look-alikes rather than true oysters.
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.
Cardiff sits on flat, low-lying ground reclaimed from coastal marshland where the Taff, Ely and Rhymney rivers meet the Severn Estuary. Wooded hills rise on the city’s northern and western fringes, marking the threshold of the South Wales Valleys. The surrounding slopes hold pockets of ancient broadleaf woodland such as the Wenallt and Fforest Fawr below Castell Coch, dominated by oak, ash, beech and sycamore. These leaf-littered woods, along with Bute Park’s riverside groves, are prime ground for autumn fungi.
Cardiff has a mild maritime climate, often cloudy, windy and wet, with around 1,100 mm of rain a year. The damp, frost-light autumns from September onwards keep the woodland floor moist well into the season. Foragers can expect a long, productive autumn across the wooded hills and parkland ringing the city, with reliable flushes after the frequent rain. The mix of ancient oak-beech woodland and river valleys offers varied habitats within easy reach of the centre.
