Field mushroom
A grassland relative of cultivated button mushrooms.
Lactarius deliciosus
Русское название: Рыжик настоящий
An orange-toned mushroom associated with pine. Lactarius contains many species, and colour or latex alone is insufficient for safe identification. The surrounding trees and several other features matter to mycologists.

Never decide to eat a wild mushroom from a photograph or online description. A mistake can be fatal. For mushroom ingestion or suspected poisoning, contact emergency medical services or a poison centre immediately, even if symptoms have not appeared.

Images and brief descriptions are for learning, not for reliably identifying a specimen. Take particular care with poisonous plants and mushrooms.
Identification is never guaranteed by a photo. Scientific names are used to reduce confusion between local names.
