"Jacob Kalichman is a field mycologist from California and Tennessee. In 2010, while studying logic at Stanford University, he became devoted as an amateur to wild mushroom identification and photography. With an ongoing interest in identifying gilled mushrooms in difficult genera, he has also taken up sharing updates in mycological taxonomy. He compiled ""A compendium of generic names of agarics and Agaricales,"" published as a paper in 2020 and continually updated. He also maintains a list of suggested common names and associated guidelines for North American fungi. Jacob wrote the current edition of the National Audubon Society's Mushrooms of North America. Dr. Roo Vandegrift is a queer scientist and illustrator. He received his doctorate in mycology (the study of mushrooms and fungi) from the University of Oregon's Institute of Ecology and Evolution, focusing much of his dissertation work on the fungi at Los Cedros Biological Reserve, in Ecuador. He has published peer-reviewed research in internationally acclaimed journals and is the producer of the independent documentary film Marrow of the Mountain, which examines mining and conservation issues in the Ecuadorian Andes. He currently serves as a plant pathologist for the USDA, identifying fungi intercepted at the border to prevent the introduction of potentially devastating invasive species."
