Calongea , a new genus of truffles in the Pezizaceae (Pezizales)

[摘要] Phylogenetic analysis of the ITS and LSU rDNA ofPachyphloeusspecies from Europe and North America revealed a new truffle genus. These molecular analyses plus sequences downloaded from a BLAST search in GenBank indicated thatPachyphloeus prieguensisis within the Pezizaceae but well outside of the genusPachyphloeus . Morphological differences in the peridial and glebal hyphae and spores distinguish this genus fromPachyphloeus . We here propose the monotypic new genusCalongea , with the type speciesC. prieguensiscomb. 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 ofCalongea .
