Abstract

Pachyphlodes atropurpurea and P. excavata are described as new species of truffles based on both phylogenetic and morphological analyses. Phylogenetically these two species are clearly distinct from described species of Pachyphlodes. Morphologically, P. atropurpurea is characterized by subglobose, purple black ascomata, and ascospores with acute-tipped spines. P. excavata is characterized by its ascomata with an obvious basal and internal cavity and slender fusiform asci (150–180 × 30–40 μm).
