Interpretive Summary: Fungi including mushrooms are a diverse group of organisms. Some are associated with living plants on which they cause diseases while others occur on dead plant material breaking down and recycling organic matter. Within a group of mushrooms that decay dead woody plants, it was difficult to determine if two named species were the same or different. Specimens from around the world were examined. In addition genomic sequences representing each species were compared. Based on these data it was determined that the two names actually represented only one species. This species is redescribed and illustrated so that scientists who encounter this fungus will know what it is

Technical Abstract: Many species of the agaric genus Crepidotus are distinguished based on single, potentially variable morphological characters. Numerous collections of Crepidotus belonging to a species complex that includes C. crocophyllus and C. nephrodes were examined from Central and Eastern Europe and North America. Morphological observations were supplemented by phylogenetic analysis of nuclear ribosomal 28S DNA. Our results indicate that C. crocophyllus is a broadly distributed temperate fungus with variable pigmentation. The fungus is re-described and a taxonomic discussion provided
