Dr. K Mandrake
- Dr. K Mandrake is a scientist and mushroom advocate, and along with his co-author Virginia Haze wrote The Psilocybin Mushroom Bible (2016) and The Psilocybin Chef Cookbook (2020), published by Green Candy Press. With a Ph.D. in microbiology, Dr. K’s specific interests include fungal biology, naturally occurring psychedelics, environmental justice, and food sovereignty. As one of Doubleblind’s resident expert mycologists, Dr. K uses a science-led approach to teach others how to safely grow and consume their own mushrooms, in addition to advising on a variety of projects, from the chemical quantification of fungal alkaloids to the use of locally occurring fungi in permaculture. In between keeping on top of the latest research in fungal biology and helping out aspiring growers on the DoubleBlind Discord server, Dr. K is equally likely to be found either out in the wild foraging for interesting cooking ingredients, or in the kitchen whipping up a delicious meal or a batch of homebrew beer. Both Dr. K and Virginia are active on Instagram @themushroombible where you can learn more about the work they do in the field of psychedelic mushroom cultivation and consumption. He has been featured as an expert by Merry Jane, Uproxx, Yahoo, and others. You can hear him interviewed on The Mushroom Hour, Bootleg Avocado and Heritage Radio Network.
