Abstract: Tulostoma catimbauense and T. deltaconcavum, both collected from Neotropical region, in the Vale do Catimbau National Park, Brazil, are proposed as new to science. Detailed macro- and micromorphological descriptions, including scanning electron microscopy of the basidiospores, are provided. ITS nrDNA sequence analyses were used to investigate the phylogenetic position of these taxa in the genus Tulostoma. Discussions about related species were carried out.
