Oyster and button mushrooms are two of the most popular mushroom varieties used in cooking. Both are edible and have a mild flavor that makes them versatile ingredients in many dishes. However, they differ in their appearance, taste, and nutritional value.
Oyster mushrooms have a delicate, slightly sweet flavor and a velvety texture. They are named after their resemblance to oysters and are available in a range of colors, including gray, brown, and yellow. Oyster mushrooms are rich in protein, vitamins, and minerals, making them a healthy addition to any meal. They are also low in calories and fat, which makes them an excellent choice for those trying to maintain a healthy diet.
Button mushrooms, also known as white mushrooms, are the most commonly consumed mushroom variety in the United States. They have a mild, earthy flavor and a firm texture. Button mushrooms are versatile and can be used in a variety of dishes, including soups, stews, and stir-fries. They are also low in calories and fat and are a good source of vitamins and minerals. However, they are not as rich in nutrients as oyster mushrooms.
Identification and Characteristics
Physical Description
Oyster mushrooms and button mushrooms have distinct physical characteristics that can help differentiate them. Oyster mushrooms are typically fan-shaped with a cap that ranges from 5 to 25 cm in diameter. The cap can be smooth or slightly wrinkled, and the color can vary from white to grayish-brown. The gills on the underside of the cap are white to cream-colored. Oyster mushrooms have a firm texture and a delicate, slightly sweet flavor.
Button mushrooms, on the other hand, are small and round with a cap that ranges from 1 to 10 cm in diameter. The cap is initially rounded and becomes more convex as it matures. The color of the cap can vary from white to light brown. The gills on the underside of the cap are initially pink and then turn brown as the mushroom matures. Button mushrooms have a mild flavor and a firm texture.
Scientific Classification
Oyster mushrooms belong to the genus Pleurotus and have the scientific name Pleurotus ostreatus. Other species of oyster mushrooms include Pleurotus pulmonarius, Pleurotus citrinopileatus, and Pleurotus eryngii. Oyster mushrooms are classified as saprotrophs, meaning they obtain nutrients by decomposing dead organic matter, such as wood.
Button mushrooms belong to the genus Agaricus and have the scientific name Agaricus bisporus. There are two varieties of button mushrooms: white button and brown button. White button mushrooms are the most commonly cultivated mushrooms in the world. Button mushrooms are also saprotrophs and obtain nutrients from decomposing organic matter, such as compost.
In summary, oyster mushrooms and button mushrooms have different physical characteristics and scientific classifications. Understanding these differences can help identify and differentiate between the two types of mushrooms.
Culinary Uses and Flavors
Cooking Techniques
Both oyster mushrooms and button mushrooms are versatile in the kitchen and can be used in a variety of dishes. Button mushrooms are commonly used in stir-fries, soups, stews, and sauces.

They can also be grilled or roasted to bring out their meaty texture.
When cooking with mushrooms, it is important to note that they release a lot of water when cooked.

Additionally, mushrooms should be cleaned with a damp cloth or brush instead of washed under running water to prevent them from becoming waterlogged.
Flavor Profiles
Button mushrooms have a mild flavor and a subtle earthy taste. They are often used as a base for dishes to add texture and depth. Oyster mushrooms, on the other hand, have a more pronounced flavor and a meaty texture. They are known for their umami taste, which makes them a popular ingredient in vegan and vegetarian dishes as a meat substitute.
When it comes to pairing mushrooms with other ingredients, button mushrooms go well with herbs like thyme, rosemary, and sage, as well as with garlic and onions. Oyster mushrooms, on the other hand, pair well with soy sauce, ginger, and sesame oil to enhance their umami flavor.
Overall, both oyster mushrooms and button mushrooms are great additions to any dish. They offer different flavor profiles and textures that can be used to elevate a variety of recipes.

Cultivation and Harvesting
Growing Conditions
Oyster mushrooms and button mushrooms have different growing conditions. Oyster mushrooms grow well in a temperature range of 20-30°C and a humidity range of 80-90%. They require a substrate that is rich in nutrients and has a high water-holding capacity. Oyster mushrooms can be grown on a substrate made of straw, sawdust, or logs.
Button mushrooms, on the other hand, require a substrate that is high in nitrogen and has a low carbon-to-nitrogen ratio. They grow well in a temperature range of 12-24°C and a humidity range of 80-90%. Button mushrooms are commonly grown on a substrate made of composted manure.
In order to cultivate oyster mushrooms or button mushrooms, the substrate needs to be inoculated with mycelium. The mycelium will then grow and colonize the substrate, eventually producing fruiting bodies.
Harvesting Techniques
Oyster mushrooms and button mushrooms require different harvesting techniques. Oyster mushrooms should be harvested when the caps are fully grown but have not yet flattened out. The mushrooms should be gently twisted and pulled from the substrate.
Button mushrooms should be harvested when the caps are still closed but have reached their full size. The mushrooms should be cut off at the base using a sharp knife.
Both oyster mushrooms and button mushrooms require good air exchange and environmental conditions to fruit properly. It is important to maintain the proper temperature and humidity levels and to provide adequate air flow to the growing area.
In conclusion, oyster mushrooms and button mushrooms have different growing conditions and harvesting techniques. By understanding these differences, growers can cultivate high-quality mushrooms that are well-suited for their intended use.
Comparison and Selection
When it comes to choosing between varieties of mushrooms, it can be difficult to know where to start. Button and oyster mushrooms are two of the most popular types, each with its own unique flavor and texture. Here is a brief comparison of the two to help you decide which one to choose.
Choosing Between Varieties
Button mushrooms, also known as cremini or white mushrooms, are the most commonly cultivated and consumed mushrooms worldwide.

Storage and Shelf Life
When it comes to storage and shelf life, both button and oyster mushrooms are fairly delicate and should be used within a few days of purchase. To extend their shelf life, store them in a paper bag in the refrigerator. Avoid storing them in a plastic bag, as this can cause them to become slimy and spoil more quickly.
King oyster mushrooms, also known as king trumpet or French horn mushrooms, have a longer shelf life than most other mushroom varieties. They have a meaty texture and a mild, nutty flavor that pairs well with a variety of dishes.
In summary, both button and oyster mushrooms are delicious and versatile, with their own unique flavor and texture.
