HOWEVER; a large portion of the Mushroom Industry is corrupt. ​Come read this article if you want to find out the Dirty Secret in the Mushroom Industry and how to choose an Authentic Mushroom Supplement.

  1. How do you use, eat, fairy fingers. I am interested in the anti tumor benefits. I found a few patches of them while looking for chanterelles. I live in Jefferson county, Mo. Do you dry them?Saute?Any information would be appreciated. Thank you.

    • Hi John,

      It’s not really a mushroom you cook. If you eat it raw it will essentially just melt in your mouth due to how watery and fragile it is.
