Abstract
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.
