A fairly common species of oceanic forests in Oregon has long been filed under Graphina sp. The purpose of this paper is to resolve the disposition of this species. The Pacific Northwest taxon is here identified with Graphis pergracilis (Zahlbr.) Lücking & A. W. Archer, previously known from the Paleotropics. A similar European taxon previously known under the name Graphina anguina auct. and Graphis britannica Staiger is here renamed G. inustuloides Lücking, after discovering that the nomenclature of this species has been misapplied. Graphis pergracilis and G. inustuloides have very similar ascospores but differ morphologically, the first representing a typical Graphis with lineola-type lirellae, whereas the second resembles the genera Phaeographis and Platygramme in lirellae morphology.
