Two novel Tuber species (Tuberaceae, Pezizales) in the Latisporum Group from China

Recent taxonomic and molecular studies on Tuber in China have revealed several new species. Here we propose Tuber polymorphosporum and T. baoshanense as new species. These species are described from Yunnan Province and differ in a combination of morphological features including ascoma color, peridium structure and ascospore shape and size. These two new taxa have phylogenetic affinity to T. latisporum and T. alboumbilicum, respectively, described from the southwest China. Phylogenetic placements of these novel Tuber species in the Latisporum group are presented here.
