Pisolithus arhizus, commonly known as the dead man's foot, dyeball,[1] pardebal, or Bohemian truffle, is a widespread earth-ball like fungus, which may in fact be several closely related species. This puffball's black viscous gel is used as a natural dye for clothes.[2] Pisolithus arhizus is a major component in mycorrhizal fungus mixtures that are used in gardening as powerful root stimulators.[3] It is inedible.[4]
