AI-generated description

Pleurotus dryinus is a species of edible mushroom that grows on deciduous trees, particularly willow and alder. In St. Petersburg and Leningrad Oblast, it is commonly found in urban parks and along rivers, fruiting from July to October. In north-western Russia, it is widespread in moist areas with abundant tree cover, often forming large clusters on stumps and logs. The fungus has a fan-shaped or oyster-like cap, 3-8 cm wide, with a smooth grayish-brown surface and white gills. Its stem is short and stout, typically 1-3 cm long. Local populations of Pleurotus dryinus in the region are considered abundant and widely distributed.
