Field mushroom
A grassland relative of cultivated button mushrooms.
Hydnum repandum
Русское название: Ежовик жёлтый
A woodland fungus with small tooth-like structures beneath the cap rather than gills or pores. Several related taxa exist and regional differences occur; shape alone is not an edibility test.

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.
