Abstract

Five corticolous taxa of sorediate Ramalinae which occur in the tropics and subtropics are shown to comprise the tropical component of the otherwise temperate Ramalina farinacea complex. Their morphology, anatomy, chemistry, ecology and distribution are discussed. Ramalina pacifica Asah., R. nervulosa (Müll. Arg.) des Abb., R. dumeticola Krog & Swinscow and R. luciae Mohlo et al., were investigated together with an unnamed acid-deficient taxon. Ramalina nervulosa and R. pacifica are maintained as species while the remainder are considered as varieties of these species; viz. R. nervulosa var. dumeticola (Krog & Swinscow) comb. nov., R. nervulosa var. luciae (Mohlo et al.) comb. nov., and R. pacifica var. inacida var. nov.
