Elaphomyces tropicalis is described as a new species based on morphological characters and molecular phylogenetic analysis of the ITS rDNA sequence. Sequences of E. tropicalis formed a distinct clade close to E. hassiacus, and sister to E. granulatus and E. asperulus. Elaphomyces tropicalis is not closely related to the E. papillatus clade. Morphologically, E. tropicalis is similar to E. (subsect Papillati) papillatus var. striatosporus with its crested spore ornamentation, but differs by having larger ascomata and different associated hosts. Shorea selanica and S. leprosula are the presumed hosts of E. tropicalis. This is the first report of an Elaphomyces species with Shorea species thus widening the previously known Elaphomyces host range.
