Winter — mushrooms tagged «Winter»

For most people, winter and mushrooms don't go together. But for a true mycologist, the forest is never empty. The winter season (December — February) offers a very narrow but remarkably interesting (and completely safe) range of mushrooms.

Winter mushrooms have evolved unique survival mechanisms. Their cells contain a kind of biological "antifreeze" (cryoprotectants) that keeps ice crystals from tearing the cell membranes. When a -10°C frost hits, these mushrooms simply freeze solid, turning into a lump of ice. And as soon as a thaw sets in (the temperature rises above zero), they thaw out and keep growing, keeping their perfect flavor and springiness.

What to pick under the snow?

1. Velvet shank (Flammulina velutipes):

The undisputed king of the winter forest. It's a pretty, honey-yellow or orange mushroom that grows in clusters on old trunks of broadleaf trees (willows, poplars, lindens, apple trees). Its stem is dark brown and velvety, and the cap is often covered with sticky slime (especially during a thaw). Velvet shank is a delicacy that the Japanese cultivate on an industrial scale and sell under the name "Enoki". You can pick it straight from under the snow.

2. Oyster mushroom (Pleurotus ostreatus):

The familiar "store-bought" oyster mushroom is, in the wild, a late-autumn and winter mushroom. It grows in masses of gray cascades on dead trunks in November and overwinters on the wood just fine. You can "chop" it off with a knife in its frozen state all winter long.

3. Jelly ear (Auricularia auricula-judae):

A gelatinous brown mushroom that looks like a real human ear. It grows on elder branches. This mushroom is hugely popular in Asian cooking (added to soups and noodles for a crunchy texture). In winter it looks like a hard lump of ice, but once brought home it thaws into soft jelly.

Winter foraging safety

David Arora notes that winter foraging is the safest of the year.

In January or February you simply won't find a death cap, a fibrecap or a poisonous Galerina in the forest — their mycelium is dormant and their fruiting bodies rotted long ago. If you see a yellow mushroom growing in a cluster on a tree during a January thaw, it is guaranteed to be velvet shank.

Questions and answers

How do you cook velvet shanks that froze in the forest?
If you bring home velvet shank frozen "rock-solid", just put it in a bowl of cold water (not warm and not hot!). It will thaw slowly, and the caps will become soft and slippery. Velvet shank stems are usually tough, so they are cut off, and the caps are fried or made into a fragrant soup.
Can you get poisoned if a winter mushroom has frozen and thawed many times?
Unlike summer porcini, which spoil after the very first frost in the forest, velvet shank and oyster mushrooms have evolved to cope with constant freeze/thaw cycles. They do not produce decay toxins during winter thaws.
