Sarcodon colombiensis sp. nov., Sarcodon rufogriseus sp. nov., Sarcodon pallidogriseus sp. nov., and Sarcodon bairdii sp. nov. are described as new to science. These fungi occur in forests dominated by the ECM trees Pseudomonotes tropenbosii (Dipterocarpaceae), Dicymbe uaiparuensis and D. stipitata (Fabaceae subfam. Caesalpinioideae). These records bring the number of Sarcodon species known from the Neotropics to 10, and demonstrate that, while being less diverse in the tropics relative to temperate and boreal regions, the genus has a wider distribution and putative host range than previously thought. These four species are also the first records of the genus in Colombia. Each of the new species possesses the accepted diagnostic characters for the genus: pileate-stipitate stature, a dentate hymenophore, determinate basidiomata development, fleshy, non-zonate context, and brown, tuberculate basidiospores. Molecular phylogenetic analysis corroborated the generic placement of the species, and, in combination with morphological characters, confirmed that they are new to science. Macromorphological, micromorphological, habitat, a taxonomic key, and DNA sequence data from the nuc rDNA internal transcribed spacer region (ITS) is provided for S. colombiensis, S. rufogriseus, S. pallidogriseus, and S. bairdii. } }
