Observation 272546: Hemipholiota populnea (Pers.) Bon


This specimen was collected by a student of Santa Fe Prep back in February and given to Dr. Roger S. Peterson for identification/sakekeeping. Dr. Peterson is a retired botanist and mycologist, and a former professor at St. John’s College in Santa Fe, New Mexico. He manages Santa Fe’s only herbarium located at (but not technically part of) the Randall Davey Audubon Center. I contacted him during a recent trip to New Mexico, where he invited me to his home. He had described this then unidentified agaric over the phone, and during our meeting, we set to work elucidating its rightful name.

Smith and Hesler’s The North American Species of Pholiota specifically mentions an especially large specimen of P. destruens from Santa Fe collected on Populus by Barrows and Isaacs. This and the rest of the description, plus an underwhelming photograph of an immature individual in Rogers and Phillips, along with further confirmation from Fungi on Plants and Plant Products in the United States (APS Press, St. Paul, Minnesota, 1989), all neatly clinched the ID. I did not observe cheilocystidia. If they were present, they did not exceed the hymenium.
