Abstract: Typification plays a crucial role in mycological taxonomy as it ensures nomenclatural stability and anchors species names to clearly defined reference material. This is particularly critical when original material is incomplete, poorly preserved, or lacks molecular data, since reliable reference points are essential for accurate species delimitation and consistent phylogenetic interpretation. Here, typifications are proposed for two nivicolous Peziza species. For Galactinia nivalis R. Heim & L. Rémy, a lectotype is designated from the original illustrations, and the holotype of Peziza fortoulii Donadini, a later synonym, serves as a supporting epitype. For Peziza heimii Pfister, the holotype in the MNHN herbarium (PC) is unsuitable for genetic characterization, and thus a supporting epitype is designated. In both cases, sequences from the epitypes are already available. These typifications strengthen nomenclatural stability and provide a robust foundation for future taxonomic, morphological, and molecular studies on nivicolous taxa within Peziza.
