How are Oyster doing in Gelderland this October?

Oyster usually come up in Gelderland from January to December, and right now they’re at 30% and building.

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.

Pleurotus ostreatus is a carnivorous fungus that secretes toxins to paralyse and digest tiny nematode worms, supplementing the nitrogen it gets from rotting wood.

Grows in overlapping shelves on dead and dying broadleaf trees, especially beech and poplar, on stumps, logs and standing trunks. It is a wood-rotting fungus and does not grow on the ground.

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.

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 (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.
