Identification
White cap, gills pink → chocolate-brown, thin ring, white flesh. On grassland soil.
Edibility
Edible and fine — the cultivated bisporus' wild cousin.
How not to confuse it — two checks
- Yellow staining at the stem base + chemical smell → yellow-stainer, discard.
- Any volva/sac at the base → could be an amanita button — excavate the base, don't pull.
