Common蘑菇科🍽 Reported Edible (Wild)

Reference sources describe this as an edible wild fungus. This guide provides no basis whatsoever for foraging or consumption.

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 white; gills pink, darkening to deep brown with age
Stem with a thin ring; base not swollen and lacks a volva
Grows in meadows and pastures, with a pleasant smell

ID notes are compiled by AI from public sources, not reviewed by a mycologist, for learning only — never a basis for foraging.

Fun Fact

Pink gills that darken to deep brown with age are a hallmark of the Agaricus genus; if the gills stay pure white, be wary — that could signal an Amanita instead.
