Field mushroom
A grassland relative of cultivated button mushrooms.
Craterellus cornucopioides
Русское название: Вороночник рожковидный
A dark funnel-shaped fungus widely known in culinary settings. It can be difficult to notice among leaf litter. Even a visually memorable shape does not establish that a particular wild find is safe to consume.

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.
