Morphological revision and phylogenetic analyses, based on nrITS and nrLSU, of specimens previously considered to be member of the “Inonotus linteus” species complex from in South America reveal a new species of Tropicoporus, here named T. drechsleri. It is a parasitic polypore restricted to the seasonally dry tropical forests of subtropical South America. Illustrations, taxonomic analyses and a discussion are presented, and a key to the Tropicoporus species in the Neotropics is provided.
