Common蘑菇科🍽 Cultivated Edible
A commercially cultivated edible fungus. Buy wild specimens only through reputable, regulated sources.
The same species can be described differently across regions and stages of maturity, and countless look-alike species cannot be told apart by eye. Never use the information on this page to judge whether a real mushroom is safe to eat.
How to Tell
- Cap rounded, white or brown; gills pink, aging to dark brown
- Stem with a thin ring; base lacks a volva
- Almost only seen in cultivation, very rare in the wild
ID notes are compiled by AI from public sources, not reviewed by a mycologist, for learning only — never a basis for foraging.
