Two New Species of Ramalina (Ramalinaceae, Ascomycota) from Korea

Abstract

Two new species, Ramalina intestiniformis Kashiw. & K. H. Moon and R. sphaerophora Kashiw. & K. H. Moon, are described from Korea. Ramalina intestiniformis, a maritime species, resembles R. almquistii Vain., but it differs by having irregularly but totally inflated lobes throughout the branches, continuous medullary hyphae, and shortly fusiform ascospores. Ramalina sphaerophora resembles R. kurokawae Kashiw. and R. yasudae Räsänen, but it differs in having semi-corticate spherical nodules instead of soralia. Both species are known only from Korea up to now.
