Field mushroom
A grassland relative of cultivated button mushrooms.
Leccinum scabrum
Русское название: Подберёзовик обыкновенный
A bolete associated with birch trees. Leccinum species can be taxonomically difficult and scientific names may change with research. A rough habitat match is not enough to identify a wild mushroom safely.

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.

Identification is never guaranteed by a photo. Scientific names are used to reduce confusion between local names.
