Peziza oliviae, P. lohjaoensis, P. montirivicola and a new species from Norway form a well-supported clade within the Peziza s. str. group based on study of the internal transcribed spacer + 5.8S rRNA gene, large subunit rRNA gene and the 6–7 region of the DNA-dependent RNA polymerase II gene. Like P. oliviae and P. montirivicola, the new species, P. nordica, is distinctly stipitate and occurs on wood that has been inundated by fresh water. These species also have paraphyses with yellow vacuolar inclusions. They fruit early in the season or at high elevations and are presumed to be saprobic. A discussion of application of the name Peziza is given.
