Abstract

Six species of Lecanora with multispored asci (multispored species) viz., L. flavothallina, L. himachalensis, L. jatoliensis, L. pruinomarginata, L. shimlaensis, and L. uttarkashiensis are described as new to science. Lecanora flavothallina is characterized by having characteristic yellow pigments at the thallus margin, L. himachalensis is characterized by having a chlarotera-type epihymenium and the presence of hypoprotocetraric acid, L. jatoliensis has pruinose apothecial discs and usnic acid, L. shimlaensis is characterized by having dark brown to black apothecial discs, and an allophana-type amphithecium. L. pruinomarginata has whitish pruinose apothecial margins and fumarprotocetraric acid, while L. uttarkashiensis is characterized by having orange-brown epruinose apothecial discs and zeorin. All six species are reported from Himalayan regions at elevations of 2000 to 3800 m. An updated world key to the known multispored species of Lecanora is provided.
