The tree oyster is very simple in cultivation. The mycelium of this pleurotus species is very robust and therefore very popular in commercial cultivation. Fruiting bodies become 5 to 15 cm in diameter. The cap is grayish brown to violet. Pleurotus is rich in B-vitamins such as thiamine, riboflavin, and niacin, vitamin C, vitamin D (calciferol) and folic acid. One fourth of the dry matter of pleurotus is proteins, containing all essential amino acids. The most important compounds of pleurotus are lovastatin and the polysaccharide pleuran.
