Abstract

In this study we review recent collections and historical records of epigeous members of the Pezizales formerly placed in the large, heterogenous genus Peziza from temperate southern South America. Recent analyses using molecular phylogenetic methods allow placement of these species in several previously described genera in recognition of the heterogeneity of Peziza. We include species in nine genera, describe one new species (Peziza gamundiae sp. nov.), and propose one new combination (Phylloscypha nothofageti comb. nov.). We also demonstrate that Pustularia microspora is a synonym of the previously described taxon Peziza pseudosylvestris. Our purpose is to draw attention to these taxa in order to promote their collection and study in a modern framework.
