Oxneriaria immersa H.S.Asghar, R.Zulfiqar & Khalid, sp. nov. and O. insignis R.Zulfiqar & Khalid, sp. nov. (Megasporaceae) are described here as new to science, both characterized by their elongating/spreading marginal areoles. The distinguishing features of O. immersa H.S.Asghar, R.Zulfiqar & Khalid, sp. nov. are poriform-aspicilioid apothecial discs, a smaller hymenium and hypothecium (90-100 and 50-70 µm, respectively) and larger ascospores (20-25×10-15 µm). The key characters of O. insignis R.Zulfiqar & Khalid, sp. nov. are distinctly lecanorine apothecial discs, a taller hymenium and hypothecium (190-230 and 100-160 µm, respectively) and smaller ascospores (15-21×9-13 µm). Detailed morpho-anatomical descriptions and a nrITS phylogeny of both species along with a worldwide key to the genus Oxneriaria S.Y.Kondr. & Lőkös are provided.
Key words: Pakistan, Kohistan, Swat Valley, Oxneriaria, phylogeny, new species.
