The traits of oyster mushrooms
Oyster mushrooms, scientifically known as Pleurotus ostreatus, are a type of edible mushroom native to Europe, Asia, and Africa (although you can find them growing in many places in the United States Pacific Northwest).
What they look like
While you may associate mushroom anatomy with a smooth cap atop a long stem, oyster mushrooms have “gills” that extend and cover their stem. This wavy texture gives them a similar appearance to oysters – hence their name.
Oyster mushrooms come in various colors and have a fan-like or ear-like shape. Formal cultivation of the oyster mushroom began in the early 1900s and was used by German soldiers as food during WW1.
How they grow
Oyster mushrooms are saprotrophs, which means they get their nutrients, or “food,” from dead and decaying matter. For this reason, wild oyster mushrooms primarily grow on rotting wood and trees.
What they taste like
Because of their meaty flavor and chewy texture, oyster mushrooms are commonly used in cooking as meat replacements and additions to recipes like stir-fry, stews, and pasta. They are also often described as having a seafood-like flavor with a rich “briny” depth, which is why they are a popular cooking ingredient.
Each type of oyster mushroom has its unique flavor and is a must-try for all mushroom lovers!
The benefits of oyster mushrooms
Oyster mushrooms are considered functional mushrooms because of their incredible health benefits. Taking these mushrooms as supplements has even been associated with lowering cholesterol and regulating blood sugar.

Common oyster mushroom imposters
There are a variety of mushrooms that are commonly confused with oyster mushrooms. While not all of these are poisonous, if you’re foraging for wild mushrooms, it’s still a good idea to make sure you identify the correct type of oyster mushroom before consuming!
Elm oyster mushrooms
While these mushrooms aren’t poisonous, they have a much blander taste than real oyster mushrooms. You can tell them apart from oyster mushrooms by their gills, which only extend to the bottom of the cap. Real oyster mushroom gills extend all the way to the bottom of the stem and often appear to not even have a stem at all.
Ghost mushrooms
These poisonous mushrooms are bioluminescent, which means they glow in the dark! This trait gives them an obvious giveaway to tell them apart from oyster mushrooms (although you have to wait until night to see for yourself!)
Jack-O-Lantern mushrooms
These mushrooms are poisonous and can leave you with a very disruptive stomach ache and diarrhea if consumed. You can distinguish these from oyster mushrooms by their color, which is a bright orange (oyster mushrooms only come in yellow!)
Ivory funnel mushrooms
Like the Elm Oyster, this poisonous lookalike can be distinguished because its gills are only on the cap. If you see a stem exposed, it is likely not a true oyster mushroom!
