Ten species of the lichen family Graphidaceae are treated in the ninth contribution to this series. Four species are new to science: Allographa cameroonensis Kalb & Schumm from Cameroon differs from A. grandis in having larger ascospores and in the lack of secondary lichen products. Allographa kuetchangiana Kalb & Schumm from Thailand differs from A. mexicana in having a permanent thalline cover of the ascomata and in having a whitish pruina on their top. Cruentotrema siamense Lücking & Kalb from Thailand differs from C. amazonum in having smaller ascomata and smaller ascospores. Ocellularia striata Kalb & Schumm from Thailand differs from O. jutaratiae in having smaller ascospores and in lacking the purplish, K+ greenish pigment which covers the remnants of the split proper exciple. Rhabdodiscus exutus (Hale) Kalb & Schumm is a new combination (Bas.: Ocellularia exuta Hale). Photographs of Allographa mexicana (Hale) Lücking & Kalb (including an isotype) show the variation of the ascomata and the differences to A. kuetchangiana. Allographa isidiata (Hale) Lücking & Kalb is reported from Ecuador, which is a new addition to the lichenobiota of this country and the second finding of this species after its description. Allographa plagiocarpa (Fée) Lücking & Kalb, before misidentified as A. mexicana, from Cartago Province is the second report of this species from Costa Rica. The chemistry of Ocellularia kohphanganensis Papong, Mangold & Lücking and the exact spelling of the specific epithet are corrected. Ocellularia macrocrocea Kalb is a new addition to the lichenobiota of Thailand where it is sometimes growing together with O. striata. The intraspecific variation of Ocellularia thelotremoides (Leight.) Hale ist discussed and the name is put on the correct place of the amended key to Thai Ocellularia species. Cochromatography of some Ocellularia species with a deep orange-yellow pigment together with a pure sample of skyrin in solvents A, B' and C showed identical Rf-values in all three solvent systems.
