Mycorrhizal Mushrooms

Mycorrhizal mushrooms live in a quiet trade with trees. They swap water and minerals for sugar, and that partnership is why so many of them resist the farm and reward the forager.

Caution

A partnership with living roots

These fungi wrap around or into tree roots and exchange nutrients with the tree. Neither side grows as well alone.

Because the mushroom needs a living host, most mycorrhizal species cannot be cultivated on straw or sawdust like oysters can.

Why foragers care

Many of the great wild edibles are mycorrhizal, including chanterelles and porcini. They return to the same trees year after year, so a good patch is worth remembering.

The catch

Warning

Some of the deadliest mushrooms, the Amanitas, are also mycorrhizal and grow in the same woods. A tree partner is no guarantee of a safe mushroom.

Frequently Asked Questions

Can you grow mycorrhizal mushrooms at home?
Usually not on the kitchen scale. They need a living tree partner, so unlike oyster or shiitake they cannot be farmed on straw or sawdust indoors.
Why do chanterelles come back in the same spot?
Because they are tied to living tree roots. The fungus persists in the soil with its host tree, so a productive patch tends to fruit in the same place each year.
