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 mountain
areas 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 consisting
only of the morphological base are newly divided, and several species of
Acarosporaceae in Korea are also being discovered in this situation. As a result of analysis
using internal transcribed spacer (ITS) and nuLSU gene analysis, Korean species belonged to
Acarospora and Sarcogyne clade, and Acarospora classified as the Acarospora clade was
mixed with the Polysporina group and the Sarcogyne clade is mixed with the Acarospora. We
identified 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 secondary
metabolite substance and found one new record (Sarcogyne oceanica K. Knudsen &
Kocourk). We have made a classification key for Acarospora and Sarcogyne in Korea and
reported all information together here.
