Oyster mushroom

Pleurotus ostreatus

Medicinal fungiKitchenHarvest

The easiest gourmet mushroom — food first, with a modest immune-supporting glucan bonus.

Oyster mushrooms eat almost any cellulose. They are the homesteader's first fungus. Medicine here is mostly 'eat mushrooms.' A few people react to the spores in poorly ventilated grow rooms.

Flavor

Delicate, anise-seafood when fresh, deeper when browned.
