Tuber latisporum sp. nov. and related taxa, based on morphology and DNA sequence data.
A new species of white truffles, Tuber latisporum, is described from southwestern China. This species can be distinguished from other species in the genus by its white and pubescent ascomata, pseudoparenchymatous peridium and broadly ellipsoid ascospores with alveolate reticulum. Molecular phylogenetic analyses of this and morphologically similar species using ITS sequences demonstrated that it is significantly different from other white truffles such as T. borchii, T. puberulum, T. zhongdianense, T. liui, T. dryophilum, T. magnatum, T. rapaeodorum, T. foetidum and T. maculatum. Data from ITS sequences indicate that white and black truffles are not monophyletic lineages.
