Ep. 134: Life in Amber - 50-Million-Year-Old Cordyceps & Other Fossilized Fungi (feat. George Poinar Jr. PhD)
Today on Mushroom Hour we are joined by the distinguished and prolific George Poinar, Jr. PhD. George received his Ph.D. in biology from Cornell University and spent most of his career in the Department of Entomology at the University of California at Berkeley before moving to Oregon State University, where he is a professor in the Department of Integrative Biology. His interest in the tropics, along with a passion for paleontology, culminated in the book The Amber Forest, co-authored with his wife, Roberta, and published by Princeton University Press. He is also the author of other books, including Life in Amber. In addition, he is a founder of The Amber Institute. He is a pioneer when it comes to studying associations between invertebrates and other organisms in amber. One of his projects was recently all over the news as he discovered a new genus and species of fungal entomoparasite growing out of a fossilized ant – the older mushroom growing from an ant that has ever been found!
