Edibility

EdibleTaste: Very good ★★★★

This mushroom has a soft texture and a strong, distinctive flavor described as floury, mealy, or similar to melon rind. Foragers must exercise great caution as it can be confused with the dangerously poisonous Livid Pinkgill, which also fruits in spring and has a mealy smell, and deadly white Clitocybe species that may grow in the same habitat. While considered a delicacy, some people find the taste overpowering.

Misidentification can be fatal. Never eat a mushroom unless you're 100% sure. This information may be inaccurate. Always consult multiple sources.

Nutrient Source
