Ramalina cinereovirens and R. subdecumbens (Ramalinaceae, Ascomycotina), Two New Species from Korea

Abstract

Two new lichen species, Ramalina cinereovirens Kashiw., K.H.Moon & J.E.Han and R. subdecumbens Kashiw., K.H.Moon & J.E.Han, are described from Korea. Ramalina cinereovirens resembles R. litoralis Asahina, a maritime species commonly found in East Asia, but it differs by having solid branches with isidial spinules. Ramalina subdecumbens resembles R. exilis Asahina, a species described from Japan, but the latter species differs in having erect branches with terminal soralia. Both species are known only from Korea.
