A new lichenicolous ascomycete, Arthonia diorygmae, is described from the thallus and ascomata of Diorygma junghuhnii. The new species is characterized by rounded to irregular, applanate to convex ascomata up to 0·3 mm in diameter, a slightly whitish pruinose disc, transversely 1-septate, hyaline to greyish ascospores (13–)14–15(–21)×5–7 µm, and its lichenicolous habitat. It is known from the subtropical region of the Western Ghats in India and appears to be widespread due to the large … Read more... 

Orientophila corticola is described as a new lichen-forming fungus from South Korea. The new species is distinguishable from other Orientophila species by the substrate preference to tree barks and the habitat specificity to inland areas. Molecular analyses applying internal transcribed spacer (ITS) and mito- chondrial small subunit (mtSSU) sequences clearly classify O. corticola as a distinct species in the genus Orientophila. A surrogate key is provided to assist in the identification of all 13 … Read more... 

Nephroma arcticum (L.) Torss., a beautiful lichen with green algae as gonidiat occurring in northern hemisphere including Japan, was studied chemically at first by Hesse15, who isolated usnic acid and a hydrocarbon nephrin C^H*, and by Zopf), who isolated zeorin beside them. In 1960 Wetmore reported the occurrence of a carotenoid as the prominent ingredient together with nephrin (in 58% specimens) and zeorin (in 63% specimens) in this species. As the conclusive faetor of his so-called "carotenoid", … Read more...
