Elm Oyster Mushroom
Scientific name: Hypsizygus ulmarius
Synonyms: Ulm Oyster Mushroom, Elm Oyster, Shirotamogitake, Da Yu Mo
Distribution and habitat in nature: The Elm Oyster Mushroom is widespread in temperate climates in deciduous and mixed forests and grows primarily on elm, beech, or oak trees. Unfortunately, its population in our forests has declined sharply in recent decades, which is why this mushroom should no longer be collected. However, by growing it in your own garden, you don't have to go without this delicious mushroom specialty..
Ingredients: This mushroom is a protein-rich, low-fat edible mushroom with a high fiber content. It contains essential amino acids, B vitamins (especially B2, B3, and folic acid), and important minerals such as potassium, phosphorus, iron, and zinc. It also provides bioactive compounds such as beta-glucans and antioxidants.
Suitable substrate: Wheat straw, hardwood (particularly suitable: elm, beech, poplar, linden, maple, willow, oak)
Usage: Edible mushroom
The Elm Oyster Mushroom is a delicious edible mushroom that is often mistakenly sold as an “oyster mushroom” at markets. It can be used in cooking in the same way as oyster mushrooms, but the fruiting bodies are larger and have a slightly more intense flavor than oyster mushrooms. It turns white to light gray and light brown, depending on the substrate and location.
