The flabelliform Hymenochaete paucisetosa spec. nov. is described from Gabon. Its main character is the scantiness of setae, ten percent of which moreover have an unusual shape. The new species is compared with the more or less closely related species H. cacao, H. villosa and H. variegata. Its cultures have been studied and compared with the only three hitherto described cultures of species of Hymenochaete.
