Abstract
Rubroboletus flammeus is described as a new species from subtropical China based on morphological and molecular phylogenetic analyses. It is morphologically characterized by a red to fiery-red basidioma with a dry pileus, a context in pileus white but that in stipe bright yellow, a stipe densely covered with spots, a blue color change of tissues, and a trichoderm-type pileipellis. Detailed descriptions, color photographs of fresh basidiomata, and line drawings of microscopic features of the new species are presented. A key to the known Chinese taxa of Rubroboletus is provided.
