Identification Tips
Look for the distinctive red cap with white warts, white free gills, and a large basal bulb with concentric rings of veil remnants. Always check the base of the stem.
Interesting Facts

Safety reminder
AI mushroom identification is a best-effort estimate and can be wrong. Never use it to decide whether a mushroom is safe to handle or eat — always confirm with a qualified mycologist before any consumption.
