Abstract:
Recent collections of Tuber malacodermum from Spain, Corsica, and Mexico were compared in an integrative morphological and molecular phylogenetic framework, including study of type material. Phylogenetic analyses of nuc rDNA internal transcribed spacer (ITS1-5.8S-ITS2 = ITS) and nuc 28S rDNA (28S) regions showed that specimens from Spain and Corsica form a monophyletic group closely related to T. melosporum and T. rufum, whereas Mexican specimens form a clade within the T. lyonii species complex. Peridium and ascospore morphology contribute clear morphological distinctions among specimens from Spain and Corsica, Mexico, and the type specimen of T. malacodermum. Based on results of the morphological and molecular phylogenetic analyses, we assigned the specimens from Spain and Corsica to Tuber pustulatum, sp. nov., and the Mexican specimens to Tuber theleascum, sp. nov. We restrict T. malacodermum to the sole type material. Formal descriptions and illustrations of these taxa are provided.
