Abstract

Foliicolous or leaf-dwelling lichens are mostly found in (sub-)tropical rainforests; due to their sensibility to environmental changes, they may serve as biological indicators for rainforest ecosystems. In Korea, the northward shift of subtropical conditions due to global climate change has emphasized the importance of understanding foliicolous lichen diversity and distribution, as they are now increasingly found in these latitudes. This study revises the taxonomy and distribution of foliicolous species in the family Strigulaceae in Korea through ITS-based identification and multigenetic analyses using four additional genetic markers (SSU, LSU, TEF1-α, and RPB2). The results support Racoplaca pelta sp. nov. and Reticula ambigua gen. nov. et sp. nov. as distinct phylogenetic lineages. Newly obtained ITS sequences confirmed that previously misidentified specimens of Strigula subelegans (KoLRI016349 and KoLRI016333) and Racoplaca melanobapha (KoLRI016334) correspond to S. multiformis and R. pelta, respectively. In addition, the distribution of Strigulaceae, once known only from Jeju Island within Korea, was found to extend to four additional southern islands: An, Ga-geo, Geo-mun, and Gwan-mae.

揭示韩国叶生地衣的隐藏谱系：一个新的隐属和隐种的发现。

叶生地衣或居叶地衣多见于（亚）热带雨林；由于它们对环境变化的敏感性，可以作为热带雨林生态系统的生物指标。在韩国，由于全球气候变化，亚热带条件向北转移，强调了了解小叶生地衣多样性和分布的重要性，因为它们现在越来越多地出现在这些纬度。本研究利用4个附加遗传标记（SSU、LSU、TEF1-α和RPB2），通过基于its的鉴定和多遗传分析，对韩国蓟科小叶生种的分类和分布进行了修正。结果支持Racoplaca pelta sp. 11和Reticula ambigua gen. 11 . et sp. 11是不同的系统发育谱系。新获得的ITS序列证实，先前被错误鉴定的亚belegans striigula （KoLRI016349）和Racoplaca melanobapha （KoLRI016334）分别属于S. multiformis和R. pelta。此外，在韩国国内只存在于济州岛的曲曲菌科，在南部的安岛、加丘岛、巨门岛、宽梅岛等4个岛屿上也发现了分布。

期刊介绍： Mycobiology is an international journal devoted to the publication of fundamental and applied investigations on all aspects of mycology and their traditional allies. It is published quarterly and is the official publication of the Korean Society of Mycology. Mycobiology publishes reports of basic research on fungi and fungus-like organisms, including yeasts, filamentous fungi, lichen fungi, oomycetes, moulds, and mushroom. Topics also include molecular and cellular biology, biochemistry, metabolism, developmental biology, environmental mycology, evolution, ecology, taxonomy and systematics, genetics/genomics, fungal pathogen and disease control, physiology, and industrial biotechnology using fungi.
