Eight new lichen species and 88 new records from Sri Lanka

Abstract

Abstract Preliminary results are presented of a project aiming to explore the lichen biodiversity in Sri Lanka. The following mostly corticolous (one saxicolous) new species are described: Arthonia karunaratnei with dark brown, round apothecia in groups that are surrounded by a bright orange area, with ascospores 2-septate, 9.0–10.5 × 3.5–4.5 μm; Enterographa wijesundarae with sessile, pruinose apothecia with thin margins that are higher than the disc, with ascospores 13–17-septate, 50–60 × 4.5–5.5 μm, without substances; Fellhanera stipitata with convex, brown apothecia, fusiform to clavate, 5–7-septate ascospores of 21–24.5 × 2.0–2.5 μm, and sessile to tubular pycnidia with conidia 4.5–5.5 × 1.5–2.0 μm; Malmidea plicata which is similar to M. vinosa but with folded thallus and smaller ascospores; Phlyctis lueckingii with ca. 0.2–0.3 mm large, grey-pruinose apothecia in dense groups and fusiform 7-septate ascospores of 27–29 × 5.5–6.5 μm; thallus with norstictic acid.; Porina viridipustulata with numerou...
