Abstract
Lichen genus Stereocaulon (Schreb.) Hoffm is distributed throughout the world. Although 15 Stereocaulon species have been recorded in Korea, no detailed taxonomic or revisionary research has been conducted for nearly two decades. In this study, we collected 260 putative Stereocaulon spp. samples and identified the species based on morphological, chemical, and molecular characteristics. From the collected samples, 10 species of Stereocaulon were identified, nine of which had already been reported, although this was the first report for the tenth, S. octomerellum Hue, in Korea. General characteristics of Stereocaulon spp. include coralloid phyllocladia and tubercular cephalodia; however, the specimen first collected in Korea was a rare species with tomentum on the pseudopodetia. The specimen of S. octomerellum is characterized by the presence of a primary thallus, granule to short coralloid phyllocladia, and pseudopodetia up to 1 cm in size, with tubercular cephalodia. To determine the phylogeny of the specimens, we compared the ITS sequences of ribosomal DNA and the b-tubulin gene sequences. Phylogenetic analysis showed that the Korean Stereocaulon species were monophyletic and placed in the previous phylogenetic classification. Species of S. intermedium and S. exutum, however, were polyphyletic, and are morphologically variable and widespread species. Overall, we present here detailed morphological and chemical descriptions of each species identified and a revised key of all known Stereocaulon species in South Korea.
