How are Oyster doing in Köln this October?

Mushroom season in Köln, Germany is building right now, with oyster sitting at 24% today. The typical season runs January to December, and we’re in October now

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.

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.

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.

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.

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 (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.
