How are Oyster doing in Västernorrland this October?

This week’s oyster forecast for Västernorrland, Sweden reads 10% 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.

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 (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.

Västernorrland rises from the indented Gulf of Bothnia shoreline into rugged, forested uplands cut by the broad river valleys of the Ångermanälven and Indalsälven. Its coast is famous for the High Coast (Höga Kusten), where steep hills and skerries climb from the sea thanks to the world’s fastest post-glacial land uplift. This is boreal taiga country, dominated by Norway spruce and Scots pine mixed with birch and aspen. The richest mushroom ground is in older spruce forest, mossy pine heaths, and the damp birch and bog margins along the valleys.

The climate is humid and continental, with long cold snowy winters and short cool summers. Rain is common in late summer and early autumn, keeping the forest floor reliably moist for fungi. Foragers can expect classic Nordic woodland species, with chanterelles, porcini and other boletes flourishing in spruce and pine stands. Forests are vast and lightly trafficked, and Sweden’s right of public access (allemansrätten) makes them open to walk and pick.
