This specimen was very fresh and did not drop but a few spore on the glass slide. Dr. Andew Methven and Dr. Walter Sundber along with expert amature mycologist Jay Justice confirmed the identification. This species is commonly and incorrectly labeled Meripilus giganteus in many field guides. Meripilus giganteus does not occur in North America. Close examination by Dr. Methven (see annotation above) combined with the 2015 DNA analysis confirmed that this specimen is Meripilus sumstinei.
