One of the most easily recognized genera of boletes is Strobilomyces, represented by taxa on most continents. At least in the Northern Hemisphere, early European species epithets are being applied to local taxa. Among these epithets in common use are S. strobilaceus and S. floccopus, sanctioned (as Boletus) by Fries. Contemporary with these is also Boletus strobiliformis, although not sanctioned. All three names, however, have been without acceptable type specimens, so identifications and diagnoses have remained insecure. This paper designates type specimens for these epithets as a prerequisite for accurate assessment of taxa. Comparison of morphological characters and sequences of ITS region of nrDNA gathered from type and additional material suggest existence of only a single European species, correctly named S. strobilaceus.
