Hemimycena lactea
What You Should Know
Hemimycena lactea is a white or creamy fungus that is less than 5 cm across, conical or bell-shaped, the margins becoming wavy and irregular when expanded and lined when moist.
This inedible mushroom was first described by Christiaan Hendrik Persoon, and given its simplified Asian name by Rolf Singer in 1938. Hemimycena lactea belongs to the genus Hemimycena, and the family of the Mycenaceae.
Edible but not worthwhile – avoid.
