 The species was described as new to science in 2009 by Beatriz Ortiz @-@ Santana , William Roody , and Ernst Both in the journal Mycotaxon . The holotype material was collected at St. Joseph Peninsula State Park in Florida in January 2005 . In 2007 , Roody and Both published a short description and color photograph of the species in their field guide Mushrooms of the Southeastern United States , but this was not a valid name as it lacked a Latin description . The specific epithet abruptibulbus refers to the abruptly ( <unk> ) swollen ( <unk> ) shape of the bulb at the base of the stem .
