Pleutorus is a genus of mushrooms that includes some of the most common brown and white edible mushrooms. King oyster mushrooms is the largest species in this genus.

Culinary uses:

Most of the mushrooms in the genus Pleutorus are cultivated mushrooms that have a savory flavor. This is especially true of king oyster mushrooms, which are also called king trumpet mushrooms. King oyster mushrooms have little flavor when they are raw but develop a savory flavor (umami) during the cooking process. However, they are nice when served raw as carpaccio.

Just like button mushrooms, king oyster mushrooms are available in brown and white. The flavor of king oyster mushrooms is also similar to that of button mushrooms.

Other uses:

Like some other Pleurotus species, P. eryngii attacks nematodes and may provide a control method for these parasites when they infect cats and dogs.1

Nutritional information:

King oyster mushrooms are low in sodium, and very low in saturated fat and cholesterol. They are a good source of protein, thiamin, vitamin B6, and several minerals. They also contain high amounts of the amino acid ergothioneine, which is an antioxidant that can help reduce the risk of chronic diseases such as cancer.

King Trumpet mushrooms contain high amounts of the naturally occurring amino acid ergothioneine, which is an antioxidant. This particular antioxidant is stored in organs like the liver and kidneys and helps reduce risk of chronic disease. King trumpet mushrooms also contain other important antioxidants. King oyster mushrooms have been studied for their ability to lower cholesterol levels, which may be a result of the presence of "lovastat..", a cholesterol blocker.

Medical uses:

In 1951, an antibiotically active substance called pleuromulin (also known as pleuromutilin) was isolated from this mushroom. And today, chemical modifications of this substance are used for various therapeutic purposes. For example, tiamulin (tiamulin hydrogen fumarate) is a well-known active substance used in drug therapy.2

Pleurotus eryngii may contain chemicals that stimulate the immune system. Dietary intake of Pleurotus eryngii may function as cholesterol-lowering dietary agent.1

Distribution:

Brown king oyster mushrooms are found in Southern, Eastern, and Western Europe and are found growing on the roots of herbs.

General information:

Pleurotus eryngii (also known as king trumpet mushroom, French horn mushroom, king oyster mushroom, king brown mushroom, boletus of the steppes, trumpet royale, aliʻi oyster) is an edible mushroom native to Mediterranean regions of Europe, the Middle East, and North Africa, but also grown in many parts of Asia. P. eryngii is the largest species in the oyster mushroom genus, Pleurotus, which also contains the oyster mushroom Pleurotus ostreatus. It has a thick, meaty white stem and a small tan cap (in young specimens). Its natural range extends from the Atlantic Ocean through the Mediterranean Basin and Central Europe into Western Asia and India. Unlike other species of Pleurotus, which are primarily wood-decay fungi, the P. eryngii complex are also weak parasites on the roots of herbaceous plants, although they may also be cultured on organic wastes.1
