Abstract
The controversial nomenclatural problem concerning the fungi causing the ink spot disease of poplar is discussed in detail. It is concluded that the correct name of the eastern species is Ciborinia whetzelii (Seaver) Seaver and that the western species does not possess a legitimate name. Ciborinia seaveri nom. nov. is proposed for this fungus. Two other species of Ciborinia on Populus are described from specimens and manuscript notes of the late Professor H. H. Whetzel, C. pseudobifrons Whet. sp. nov. and C. davidsoniana Whet. sp. nov.Keywords
