Extract from Wikipedia article: Pleurotus ostreatus, the pearl oyster mushroom or tree oyster mushroom, is a common edible mushroom. It was first cultivated in Germany as a subsistence measure during World War I and is now grown commercially around the world for food. It is related to the similarly cultivated king oyster mushroom. Oyster mushrooms can also be used industrially for mycoremediation purposes.
Pleurotus ostreatus is a widely distributed edible fungus that grows on trees, stumps, and other decaying wood. In St. Petersburg, Leningrad Oblast, and north-western Russia, it typically fruits from June to October, preferring deciduous trees such as birch, aspen, and willow. The fungus is commonly found in urban parks, forests, and along rivers, with a frequency of occurrence increasing in areas with high levels of moisture and humidity. Its growth habits and ecological preferences in the region are influenced by the local climate, with optimal temperatures for growth ranging from 10 to 20°C.
