 The fruit bodies of Boletus abruptibulbus grow singly or in groups in sand . The species is known only from the Gulf Coast of the Florida Panhandle , where fruiting occurs on older sand dunes , particularly in areas where the habit changes from coastal scrub to oak @-@ pine woods . This latter habitat is characterized by the presence of the tree species Sand Live Oak ( Quercus <unk> ) , Myrtle Oak ( Q. <unk> ) , and Sand Pine ( Pinus clausa ) . Fruiting occurs from December to March . Boletus abruptibulbus is one of only three North American Boletaceae species that occur in coastal sand dunes ; the others are Leccinum arenicola , found in New Brunswick , Canada , and <unk> arenicola , described from Oregon .
