During the revision of the Antrodia species from the Atlantic Forest in southern Brazil, some specimens collected on dead branches of Baccharis (Asteraceae) were found to represent an undescribed species, Antrodia neotropica sp. nov. Morphologically, this new species is characterized by resupinate to effused-reflexed basidiomata with a cream to brown pore surface, a dimitic hyphal system and basidiospores that are cylindrical to subcylindrical, in dorsi-ventral view with an obovoid aspect, and from the side-view present a sigmoid ventral side. Molecular phylogeny inferred from nrITS and nrLSU sequence data confirmed that this species belongs to the Antrodia s.s. clade, closely related to European and North American species, A. serpens and A. heteromorpha. Its relationships within Antrodia s.s. as well as biological and morphological characters of Antrodia s.s. are discussed.
