I am writing a term paper about medically relevant mushrooms and I need to find the scientific name for this mushroom, but all I have is a description from the book Mushrooms, Molds, and Miracles written by Lucy Kavaler, copyright 1965. It is a mushroom that grows in New Guinea that is or has been used as a contraceptive. It grows on old tree stumps 6000 feet up the slopes of the mountains. Women eat them to prevent conception. I could really use this for my paper, if anyone has any knowledge about it. Thanks.
