Abstract
|
|
|
|
Acarosporaceae is a crustose lichen and is known as a species that has more than 50 multispores,and has hyaline spores. Those taxa are often found in rock and soil in mountainareas or coastal regions in Korea, and very diverse forms and species are known. However,after an overall genetic phylogenetic analysis of carbonized ascomata in 2015, species consistingonly of the morphological base are newly divided, and several species ofAcarosporaceae in Korea are also being discovered in this situation. As a result of analysisusing internal transcribed spacer (ITS) and nuLSU gene analysis, Korean species belonged toAcarospora and Sarcogyne clade, and Acarospora classified as the Acarospora clade wasmixed with the Polysporina group and the Sarcogyne clade is mixed with the Acarospora. Weidentified two new species (Acarospora beangnokdamensis J. S. Park & S. O. Oh, sp. nov.,Sarcogyne jejuensis J. S. Park & S. O. Oh, sp. nov.) through morphological, molecular, and secondarymetabolite substance and found one new record (Sarcogyne oceanica K. Knudsen &Kocourk). We have made a classification key for Acarospora and Sarcogyne in Korea andreported all information together here.
