Arthonia dokdoensis sp. nov., a lichenicolous fungus from the subcosmopolitan Arthonia molendoi complex growing on crustose thalli of species of the genus Orientophila (subfamily Xanthorioideae, Teloschistaceae), as well as the lichen species Rufoplaca toktoana sp. nov. (subfamily Caloplacoideae, Teloschistaceae) similar to Rufoplaca kaernefeltiana, both from Dokdo Islands, Republic of Korea, are described, illustrated, and compared with closely related taxa. In the phylogenetic tree of the Arthoniaceae based on 12S mtSSU and RPB2 gene sequences, the phylogenetic position of the A. dokdoensis and the relationship with the A. molendoi group are illustrated, while the position of the newly described R. toktoana is confirmed by phylogenetic tree based on ITS nrDNA data.

Arthonia dokdoensis SP。nov。，一种来自地下世界的Arthonia molendoi复合物的地衣真菌，生长在Orientophila属（Xanthorioideae科，Telosschistaceae科）的地壳rust上，以及地衣物种Rufoplaca toktoana sp。十一月 分别描述，说明并与近亲类群比较，它们均与大韩民国鲁弗普拉卡·卡尼菲尔蒂亚娜（Rufoplaca kaernefeltiana）相似（亚科Caloplacoideae，Telosschistaceae）。在的系统发育树Arthoniaceae基于12S mtSSU和RPB2基因序列，所述的系统发育位置A. dokdoensis并说明了与柔毛曲霉的关系，而新描述的R. toktoana的位置由基于ITS nrDNA数据的系统树确定。
