Pseudochapsa is a genus of lichen-forming fungi in the family Graphidaceae. It has 19 species. It was circumscribed in 2012 by Sittiporn Parnmen, Robert Lücking, and Helge Thorsten Lumbsch, with Pseudochapsa dilatata as the type species. Pseudochapsa differs from Chapsa (the genus from which it was segregated) it that its excipulum (the rim of tissue around the apothecia) is typically brown. Additionally, its ascospores are mostly discoseptate and amyloid. The generic name combines the Greek pseudo ("false") with the genus name Chapsa.
