Abstract

Five species of Eremothecella are recorded from the Andaman Islands, two of which are described as new: Eremothecella ajaysinghii Jagad. Ram & G. P. Sinha and E. nicobarica Jagad. Ram & G. P. Sinha. Eremothecella ajaysinghii has whitish grey, pruinose ascomata and 8–10(–11)-septate ascospores, while E. nicobarica has non-pruinose ascomata and (14–)15–17-septate ascospores. Eremothecella calamicola Syd., E. macrosperma (Zahlbr.) Sérus. and E. variratae (Aptroot & Sipman) Sérus. are reported as new records for India. An updated worldwide key to species of the genus is presented.
