The new genus and species, is described from Jeju Island, Korea. This lichen is characterized by saxicolous, crustose, pale greenish-gray, partly finely filamentous, matt, smooth thallus, prominent convex brown to dark brown ascomata with a concolorous margin constricted at the dark brown base, 300-800 μm diameter, 200-250 μm high, without a distinct proper margin, adhering to the substratum ending in a minute byssoid white external part of cylindrical cells, fusiform 3-5 septate ascospores (17-23 × 4-5 μm). Phylogenetic analyses using ITS and mtSSU sequences place in the (Lecanorales). The new taxon is closely related to , a cosmopolitan group of foliicolous lichens, which is most diverse in the tropics. Like , also forms a byssoid apothecial margin.
这个新属和新物种是在韩国济州岛发现并被描述的。这种地衣的特征为：生于岩石上，呈壳状，淡绿灰色，部分呈细丝状，无光泽，表面光滑的叶状体；具突出的、凸起的、棕色至深棕色的子囊盘，边缘同色，在深棕色基部处收缩，直径300 - 800μm，高200 - 250μm，无明显的真正边缘，附着于基质，末端为微小的、具丝状白色外部的圆柱形细胞；梭形，具3 - 5个隔膜的子囊孢子（17 - 23×4 - 5μm）。利用ITS和mtSSU序列进行的系统发育分析将其置于[具体分类阶元名称]（茶渍目）中。这个新分类单元与[另一相关类群名称]密切相关，[另一相关类群名称]是一类分布于全球的叶生 lichens，在热带地区最为多样。与[另一相关类群名称]一样，[新分类单元名称]也形成丝状的子囊盘边缘。
