Abstract:Tuber gibbosum Harkn., described from northern California, was originally thought to be a single, variable species that fruited from autumn through winter to spring. It became popular for culinary use in the Pacific Northwestern USA and is commercially harvested in the wild. By the late 20th century, however, it became recognized as a complex of at least two species. We conducted morphological and phylogenetic studies of the complex to determine how many species it might contain and how they differed geographically and seasonally. Phylogenetic analyses conducted on the LSU region distinguished the Gibbosum clade from other major clades in Tuber, and analyses on ITS and LSU regions revealed four distinct species. Although morphologically similar in many ways, the four species proved to differ in spore size and shape and to some degree in peridial anatomy. All four have distinctive hyphal tips with irregular wall swellings emergent from the peridium at maturity; we have not seen this type of hypha in any other Tuber spp. world-wide. The three new species are named and described as T. bellisporum Bonito & Trappe, T. castellanoi Bonito & Trappe and T. oregonense Trappe, Bonito, & Rawlinson.
