Kashiwadani, H./ Moon, K.H. 2017: Two New Species of Ramalina (Ascomycotina: Ramalinaceae) from the Nansei Islands, Japan. - The Journal of Japanese Botany92(1): 27-33. [RLL Suppl.] Keywords: JAPAN/ NANSEI ISLANDS/ RAMALINA
Abstract: Two new species, Ramalina ryukyuensis Kashiw. & K. H. Moon and R. yokotae Kashiw. & K. H. Moon, from the Nansei Islands, southern Japan, are described. Ramalina ryukyuensis, a corticolous or epiphytic species on the creeping stems of Zoysia, has predominantly dichotomous branches with wide angles throughout the thallus; solid branches without soredia; round or ellipsoid pseudocyphellae; long fusiform spores of 10%A8C12.5 %A1Á 2.3%A8C2.5 %A6Ìm in size; and norstictic acid or sekikaic acid. Ramalina yokotae, an epiphytic species on Zoysia over calcareous rocks, has a hollow thallus with clearly dichotomous branches without soredia, separated perforations, and norstictic acid and sekikaic acid (%A1À). They are only known from the Nansei Islands in Japan. [New species: Ramalina ryukyuensis Kashiw. & Moon, R. yokotae Kashiw. & Moon]
