“…Following early species records from Japan (Müller 1879, Nylander 1890, Vainio 1918, Zahlbruckner 1931, research on Arthoniaceae started again in the late 20th century (Kashiwadani and Thor 1995, Thor et al 2000, Yamamoto et al 2002, Handa et al 2014. About 32 species in 8 genera are currently accepted for Japan (Kurokawa and Kashiwadani 2006, Frisch et al 2014a, Ohmura and Frisch 2016 and 18 species in Arthonia, Arthothelium and Ciniocarpon for Korea (Joshi et al 2013, Kondratyuk et al 2013, 2016, Aptroot and Moon 2014, Lee and Hur 2016. In the course of revision work on the Arthoniaceae in Japan and Korea, we frequently collected a distinctive Arthonia from the rain-shaded basal portions of trees in old-growth forests.…”

The rare and poorly known Northern Hemisphere old‐growth forest lichen Arthonia incarnata is reported for the first time for Asia from Japan and Korea. A detailed description and illustration is provided for the species based on the collections from Japan and South Korea. Bayesian and RAxML analyses of mtSSU, nLSU and RPB2 sequence data show A. incarnata to be only distantly related to the other Arthonia species hitherto sequenced and in particular to superficially similar species occurring in the same type of habitat such as A. didyma, A. spadicea and A. vinosa. For the analysis we generated new sequence data of A. incarnata for the mtSSU (5 specimens) and RPB2 (5) gene loci. Slight variation was observed in sequence data of the RPB2 gene between collections from eastern Asia and Sweden, but this is not substantiated by differences in morphology or ecological behaviour. Arthonia incarnata is confined to humid forests and only grows on parts of tree trunks shaded from precipitation and running water such as the lower side of leaning trunks or cavities at the base of trees. The species is found on trees with acidic bark, in eastern Asia mainly on Betula but also on coniferous trees and on dead wood. It was not found on bark of Salix (caprea), a common substrate for the species in Europe.

“…In our survey, we identified two species, Arthothelium ruanum and a putative new species Arthothelium punctatum . A. ruanum is dominantly distributed in Asia, including Korea [ 7 14 15 ], Europe, and North America [ 1 ]. Unlike the previously described morphological characteristics of A. ruanum [ 14 15 ], 20 specimens from Mt.…”

“…have been conducted on European species. Indeed, prior to this study, only one species, A. ruanum , was collected and described in South Korea by Joshi et al [ 14 ] and Kondratyuk et al [ 15 ]. In the present study, we extensively collected and identified Arthothelium specimens in Korea, leading to the discovery of a putative new Arthothelium species named A. punctatum , as well as an already known species.…”

A total of 121 species of lichens belonging to the genus Arthothelium have been described to date, most of which have been found in tropical regions. Here, we describe the discovery of a novel Arthothelium species for the first time in South Korea. Until now, Arthothelium ruanum was the only Arthothelium species reported in South Korea. Among the 113 specimens collected in this study, we identified A. ruanum and a putative new species, Arthothelium punctatum (J. S. Park & J.–S. Hur, sp. nov.). The diagnostic characters of A. punctatum are as follows: apothecia punctate, shortly elongate to branched, small, 0.1–0.2 mm wide, hypothecium hyaline to pale brown and obovate to broadly ellipsoid, muriform ascospores, 29.5–44.6 × 12.2–18.2 μm. The new species was found in Mt. Seokbyeong at an altitude of 790 m on smooth bark. Upon phylogenic analysis, the putative new species, A. punctatum, was separated from other Arthothelium species although the specimens analyzed were clustered with Arthoniaceae in phylogenetic trees based on both the mitochondrial small subunit (mtSSU) sequence and combined mtSSU and nuclear ribosomal large subunit sequences. Our data clearly indicate that this species is a new species belonging to the family Arthoniaceae. To elucidate the taxonomic characteristics of the new species, we provide morphological descriptions and a distribution map.

Arthonia coreana, Arthonia superpallens, and Arthonia zelkovae are new species from South Korea. All new species are in the Euarthonia tribe, based on the key characteristics of colorless hypothecium and multi-cellular spores. A. coreana has a dull brownish hypophloedal thallus without bleaching and rounded or curved big apothecia in comparison with those of Arthonia punctiformis. A. coreana consistently exhibits 4-septate ascospores, which is a distinctive characteristic that distinguishes it from other Arthonia species. A. superpallens has a white-greenish thallus, pale yellowish apothecia, and a trentepohlioid alga. However, A. superpallens has no distinct prothallus, adnate, and convex apothecia, no pycnidia, and is UV-, in contrast with related species in the Arthonia antillarum group. A. zelkovae has a white, epiphloedal thallus, brownish-black epruinose apothecia covered with a whitish bark layer, and smaller ascospores in comparison with those of A. punctiformis. A. zelkovae consists of a chlorococcoid alga, which differs from related Arthonia species such as A. punctiformis, Arthonia pinastri, and Arthonia glaucella. Although A. zelkovae is similar to Arthonia dispersa in its white-colored thallus, blackish apothecia, and the presence of a chlorococcoid photobiont, A. zelkovae differs from the latter in having larger-sized 3-septate ascospores. Arthonia cinnabarina f. marginata, A. glaucella, Arthonia ilicinella, Arthonia lapidicola, Arthonia leioplacella, Arthonia pertabescens, A. pinastri, Arthonia spadicea, and Arthonia stellaris are newly described in Korea. The diagnostic characteristics of these species are discussed and presented. An artificial key is provided to facilitate identification of Arthonia species from Northeast Asia.
