Two new species, Sarcogyne crispula and S. pakistanensis are described and illustrated from Pakistan. Sarcogyne crispula
is similar to S. praetermissa. Both have lecideine apothecia with smooth melanized margins which curl inward above the
apothecial disc and grow on calcareous rock, but they difer especially in S. crispula having larger apothecia (2–3 mm wide
vs. usually less than 1 mm) with thinner margins (50–70 vs. 70–120 μm) as well as difering in nrITS and mtSSU regions.
Sarcogyne pakistanensis is similar to S. similis. Both grow on siliceous rocks and produce psoromic acid. Sarcogyne pakistanensis difers from S. similis especially in having a lower hymenium (55–85 vs. 100–125 µm), a thinner margin [ca. 100
vs. (100–)150–200 μm], a hypothecium with dark black area, as well as difering in their nrITS regions.
