Abstract

The genus Tuber is a lineage of diverse ectomycorrhizal, hypogeous, sequestrate ascomycete fungi that are native to temperate forests in the Northern Hemisphere. Recently, many new species of Tuber have been described in North America and Asia, based on morphological characteristics and molecular data. Here we describe and illustrate a new species, Tuber incognitum, based upon phylogenetic analysis and morphological description. We also present a new record for Tuber anniae in México. These two Tuber species are distributed in the Transmexican Volcanic Belt in the states of México, Michoacán, Guanajuato, Querétaro and Tlaxcala at altitudes between 2,000 and 3,200 meters. These species are associated with Pinus (T. anniae) and Quercus forests (T. incognitum).
