摘要： Three new species of Tuber, T. albicavum, T. laojunshanense, and T. umbilicicavatum belonging to the Puberulum phylogroup, are described based on specimens collected in alpine Abies forests at 3600-4000 m, Northwest Yunnan, China. T. albicavum is distinguished by its ascomata with a single chamber of 0.5-1.8 cm diameter, with an apical opening of 0.2-0.6 cm in diameter, and light golden-brown alveolate reticulate ascospores up to 30 mu m in length; T. laojunshanense is characterized by having ascomata with a slightly tomentose surface, sometimes with a white navel, a relatively thick peridium, up to 280 mu m, and yellow-brown spores with alveolate reticulate ornamentation, up to 34 mu m in length; T. umbilicicavatum is characterized by smooth ascomata with a distinct white navel, a relatively thin peridium, up to 110 mu m, and golden or golden-brown alveolate reticulate ascospores, up to 40 mu m in length. The molecular analysis of the internal transcribed spacer region also supports that these three new species differ from previously described Tuber species.
