Golden oyster mushrooms, also known as yellow oyster mushrooms, are a variety of edible gourmet mushrooms. They are native to eastern Russia, northern China, and Japan, but have become naturalized in North America and parts of Europe. Golden oyster mushrooms are cultivated commercially and foraged in the wild, prized for their bright yellow to golden-brown caps, complex flavors, and health benefits. They are also known for their ease of cultivation and short shelf life. These mushrooms are considered invasive in some regions, impacting native fungi and ecosystems.

Golden oyster mushrooms are native to eastern Russia, northern China, and Japan
Golden oyster mushrooms, or Pleurotus citrinopileatus, are native to eastern Russia, northern China, and Japan. They are also sometimes called yellow oyster mushrooms. In Japan, they are nicknamed Phantom mushrooms due to their elusive nature. They are a popular edible mushroom in their native regions and have been growing wild since ancient times. Golden oyster mushrooms thrive in hardwood forests and are commonly found on the fallen wood, stumps, or trunks of beech, oak, elm, maple, and ash trees. They never grow on the ground and reside in subtropical to warm, temperate climates.
Golden oyster mushrooms are one of the most colourful varieties of oyster mushrooms. Their thin, delicate caps range in colour from bright daffodil yellow to golden yellow. They grow in small to medium-sized clumps, sometimes referred to as bouquets, and are comprised of many layers of tightly packed mushrooms. Like other oyster mushrooms, they grow in eye-catching clusters, making them a favourite at local farmers' markets.
Golden oyster mushrooms are cultivated commercially, usually on a medium of grain, straw, or sawdust. They are one of the most commonly cultivated mushrooms, particularly in China, due to their ease of cultivation and their ability to convert 100g of organic refuse into 50-70g of fresh mushrooms. In eastern Russia, they are called iI'mak and are one of the most popular wild edible mushrooms. Golden oyster mushrooms are a source of antioxidants and have been studied for their potential health benefits, including antihyperglycemic properties and as a source of lipid-lowering drugs.
In the wild, golden oyster mushrooms are a wood-decay fungus that commonly decays hardwoods such as elm. They have been found growing on oak, beech, and other hardwoods in addition to elm. Golden oyster mushrooms have been naturalized in several countries outside of their native range, including in the United States, Canada, and several African and Asian countries. Their vigorous range expansion has been compared to that of invasive species. While they are edible and delicious, they are non-native and can consume resources that other native mushrooms would use.

They are invasive in North America, Switzerland, Italy, Hungary, Serbia, and Germany
Golden oyster mushrooms (Pleurotus citrinopileatus) are native to the hardwood forests of eastern Russia, northern China, and Japan. They are a popular edible mushroom in these regions and are known for their ease of cultivation. However, they are considered invasive in North America, Switzerland, Italy, Hungary, Serbia, and Germany.
In North America, golden oyster mushrooms were first introduced in the early 2000s, likely due to the growing popularity of mushroom cultivation kits and the international culinary craze surrounding these mushrooms. While the exact source of their escape into the wild is unknown, it is speculated that they may have originated from a grow kit, a commercial mushroom farm, or outdoor logs inoculated with golden oyster mushrooms. As of 2025, they have been spotted in various states, including those around the Great Lakes, such as Minnesota, Wisconsin, Michigan, and New York, as well as in more distant states like Alabama, Colorado, and Texas.
The invasive nature of golden oyster mushrooms in North America poses a significant threat to native fungal biodiversity and vulnerable ecosystems. Their aggressive spread has led to concerns about the impact on native mushroom species, particularly in the Midwest, where they compete for resources with other fungi. Additionally, their rapid colonization of dead and decaying trees may accelerate the rate at which these trees fall, affecting plants and animals that depend on old trunks.
In Europe, golden oyster mushrooms have been reported in forests of Italy, Hungary, Serbia, and Germany, with Switzerland being the first European country to recognize them as invasive. The spread of these mushrooms in Europe is attributed to the international cultivation and trade of mushrooms, either intentionally as products or unintentionally through global transportation. The full scope of the impact of golden oyster mushrooms in these European countries is yet to be determined, and research in this area is ongoing.
To address the spread of golden oyster mushrooms in invaded regions, experts recommend refraining from using grow kits to prevent further introductions into the wild. Additionally, it is advised that those involved in the mushroom industry, including growers, businesses, and foragers, take proactive measures by clearly indicating that this species is invasive and should be cultivated indoors without composting.

Golden oyster mushrooms are a source of antioxidants and have been studied for their medicinal properties
Golden oyster mushrooms (Pleurotus citrinopileatus), also known as yellow oyster mushrooms, are native to the hardwood forests of eastern Russia, northern China, and Japan. They are easily identifiable by their distinctive appearance, resembling a cluster of golden-yellow petals with thin, delicate caps. Beyond their culinary uses, golden oyster mushrooms are a source of antioxidants and have been studied for their medicinal properties.
Golden oyster mushrooms contain high levels of ergothioneine, a powerful antioxidant that helps protect cells from oxidative stress and reduces or prevents cell damage caused by free radicals. This antioxidant activity may contribute to the potential health benefits associated with golden oyster mushrooms. Studies have found that oyster mushrooms may improve blood sugar levels and other aspects of health when taken as a supplement or included in the diet.
One study on hospitalized patients with type 2 diabetes showed that consuming 150 grams of oyster mushrooms three times a day for seven days reduced fasting blood sugar levels significantly. Additionally, a study of 89 participants with diabetes found that eating oyster mushrooms for seven days lowered their blood sugar, cholesterol, triglycerides, and blood pressure. Golden oyster mushrooms also contain beta-glucans, which are linked to reducing cholesterol levels and promoting heart health.
Regular consumption of golden oyster mushrooms may also contribute to a stronger immune system. Research indicates that certain polysaccharides found in these mushrooms can stimulate the activity of immune cells and enhance the body's defense mechanisms. Furthermore, the dietary fiber in golden oyster mushrooms aids digestion and supports a healthy gut microbiome, which is associated with improved immunity and better nutrient absorption.
Golden oyster mushrooms are not just valued for their health benefits but also for their culinary delights. They have a slightly nutty and mild flavor, complementing various dishes. Their delicate texture and vibrant color make them a favorite among chefs and home cooks, who enjoy preparing them in a variety of ways, including sautéing, grilling, and stir-frying.
