, , and 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. has a dull brownish hypophloedal thallus without bleaching and rounded or curved big apothecia in comparison with those of . consistently exhibits 4-septate ascospores, which is a distinctive characteristic that distinguishes it from other species. has a white-greenish thallus, pale yellowish apothecia, and a trentepohlioid alga. However, has no distinct prothallus, adnate, and convex apothecia, no pycnidia, and is UV-, in contrast with related species in the group. has a white, epiphloedal thallus, brownish-black epruinose apothecia covered with a whitish bark layer, and smaller ascospores in comparison with those of . consists of a chlorococcoid alga, which differs from related species such as , , and . Although is similar to in its white-colored thallus, blackish apothecia, and the presence of a chlorococcoid photobiont, differs from the latter in having larger-sized 3-septate ascospores. f. , , , , , , , , and are newly described in Korea. The diagnostic characteristics of these species are discussed and presented. An artificial key is provided to facilitate identification of species from Northeast Asia.
[物种名称1]、[物种名称2]和[物种名称3]是来自韩国的新物种。基于无色子实下层和多细胞孢子的关键特征,所有新物种都属于真地卷衣族。与[物种名称4]相比,[物种名称1]有暗褐色的皮下层地衣体,无褪色现象,且有圆形或弯曲的大子囊盘。[物种名称2]始终呈现4隔膜的子囊孢子,这是将其与其他[属名]物种区分开来的显著特征。[物种名称3]有白绿色的地衣体、淡黄色的子囊盘和 Trentepohlia 藻类。然而,与[类群名称]中的相关物种相比,[物种名称3]没有明显的原叶体,子囊盘贴生且凸起,没有分生孢子器,并且对紫外线不敏感。[物种名称4]有白色的皮层上地衣体,褐色至黑色的无粉子囊盘覆盖着一层白色的树皮状层,与[物种名称1]相比,子囊孢子较小。[物种名称5]由绿球藻组成,这与[相关物种1]、[相关物种2]和[相关物种3]等相关[属名]物种不同。尽管[物种名称6]在其白色地衣体、黑色子囊盘和存在绿球藻共生体方面与[物种名称5]相似,但[物种名称6]在具有较大尺寸的3隔膜子囊孢子方面与后者不同。[分类单元名称]的[变型名称1]、[变型名称2]、[变型名称3]、[变型名称4]、[变型名称5]、[变型名称6]、[变型名称7]、[变型名称8]、[变型名称9]和[变型名称10]在韩国是新描述的。讨论并呈现了这些物种的诊断特征。提供了一个人工检索表,以方便鉴定来自东北亚的[属名]物种。
