    Description

    Phylogenetic analysis of the ITS and LSU rDNA of Pachyphloeus species from Europe and North America revealed a new truffle genus. These molecular analyses plus sequences downloaded from a BLAST search in GenBank indicated that Pachyphloeus prieguensis is within the Pezizaceae but well outside of the genus Pachyphloeus. Morphological differences in the peridial and glebal hyphae and spores distinguish this genus from Pachyphloeus. We here propose the monotypic new genus Calongea, with the type species C. prieguensis comb. nov., in honor of Prof. Francisco de Diego Calonge, who has long studied the truffle fungi of Spain and participated in describing the type species of Calongea.
