Out of 10,000 dead trees ideal for growing mushrooms, only two will actually produce the elusive Reishi mushroom. Reishi have no gills like other mushrooms. Instead, they have a cork-like underside which releases spores. Fortunately, they are now cultivated in the United States, China, Japan, Korea and Taiwan. The mushrooms are produced over a course of two years from spore to harvest.

  • Black

  • White
  • Yellow
