Over 200 new lichen records from Sri Lanka, with three new species to science

Two hundred and seven lichen species are newly reported from Sri Lanka, eight of which were previously thought to be endemic in India; 91 species are new to the Indian subcontinent, and four to Asia, and three are described here as new to science: Astrothelium nitidulum which has 7-septate ascospores with diamond-shaped lumina, mostly simple ascomata in shiny olive pseudostromata and an inspersed hamathecium; Heterodermia queensberryi which is similar to Heterodermia propagulifera but with a corona of lobules around the apothecia; and Malmidea papillosa, which is similar to Malmidea granifera but has regular warts and lacks medulla in the excipulum.
