Cultivated supply is huge, so wild oysters are a chef novelty, not a gold rush. Tight, unyellowed clusters only.

Description
Shelf-like clusters on hardwood with off-center stems, decurrent white-to-cream gills, and a lilac-gray to tan cap. Spore print is lilac-gray. One of the safer beginner wood mushrooms — but still confirm gills + wood + no ring, and never confuse with small brown wood fungi.
Where it grows
Dead and dying hardwoods — aspen, cottonwood, oak, beech, elm.
How to find it
Scan standing dead and fallen hardwoods after cold rains. They often fruit in the same log for years. Winter on the coast, cooler months inland.
How to pick
Cut the cluster at the wood. Leave a pad. Trim tough bases. Use within two days; they sour fast.
Medicinal notes
Common food. Some cholesterol and immune research on cultivated Pleurotus. Not a substitute for medicine.
Psychoactive / controlled
None. Not a Psilocybe. Does not bruise blue.
Law
Legal food. Easy to cultivate legally if you want volume.
Lookalikes
Angel wings (Pleurocybella)
Pure white, thinner, on conifer. Linked to rare but serious poisonings in Japan. Know your host tree.
- Deadly galerina
Tiny, rusty-brown spores, on wood. Not a cluster of oyster shelves — but beginners mix 'wood mushrooms.'
