Resumen

El análisis filogenético del ITS y LSU rDNA de especies europeas y norteamericanas de Pachyphloeus revelan un género nuevo de trufa. Los datos moleculares de este estudio, además de las secuencias obtenidas de una búsqueda BLAST en GenBank, indican que Pachyphloeus prieguensis es un miembro de la familia Pezizaceae pero no está relacionado con ninguna otra especie hipogea o epigea de dicha familia. Encontramos diferencias morfológicas en las hifas del peridio y gleba así como en las esporas que morfológicamente distinguen éste de Pachyphloeus. Proponemos el nuevo género monotípico Calongea, con C. prieguensis comb. nov. como la especie tipo, en honor a uno de los descubridores originales, Prof. Francisco de Diego Calonge.
