Fomitiporia castilloi sp. nov. from the lowland rainforest in French Guyana is described, illustrated and its phylogenetic affinities are discussed. This species is characterized by pileate basidiomata, a plicate margin, abundant, variably shaped hymenial setae and basidiospores averaging congruent to 6 x 5 mu m. In phylogenetic inferences based on a DNA sequence dataset of four loci (5' end of the LSU, ITS-5.8S, partial tef1 and rpb2), F. castilloi occupies an isolated position, basal to a clade that is composed exclusively of Neotropical species with resupinate basidiomata. The phylogenetic inferences also provide evidence of an unreported complexity within the Neotropical taxa, with multiple clades closely related to F. apiahyna and F. texana, representing additional potential species.
