This study deals with the new records for the moss flora of Korea based on recent collections conducted by the authors and the specimens deposited at the herbarium of the National Museum of Nature and Science in Japan. We conducted field studies in Jejudo Island, Socheongdo Island, and Gangwon-do from 2015 to 2018. Jejudo Island is known as the region with the highest biodiversity on the Korean Peninsula. Socheongdo Island has a small area of 2.91 km2, but it is the only area in South Korea where the stromatolites of the Precambrian Eon are found. The limestone areas of Gangwon-do are known to have a variety of rare plants adapted to alkaline soil. In addition, about 360 Korean specimens deposited at the herbarium of the National Museum of Nature and Science in Japan (TNS) were examined. They were collected from 1914 to 1943, and their localities include Geumgangsan Mt., Baekdusan Mt., and Chailbong in North Korea. Unfortunately, there are no specimens left in South Korea, which had been collected at the beginning of the 20th century. Therefore, the specimens deposited at TNS are valuable materials to study Korean Bryofloa. Park and Choi (2007) compiled a checklist of Korean bryophytes, and list 291 genera and 645 species of mosses from Korea. We added 34 moss species new to the flora of Korean bryophytes.
Materials and Methods
Field studies were carried out from 2015 to 2018, and a total of ca. 1,593 bryophyte specimens were collected. About 360 moss specimens of Korea are kept at TNS. The specimens newly obtained through this study are kept in the National Institute of Biological Resources (KB), and some duplicates are also kept in the herbaria of the TNS and the Hiroshima University (HIRO) in Japan.
Results and Discussion
New records
A total of 34 mosses are new to Korea based on the collections made by the authors mainly in Jejudo Island. Newly added mosses are organized as 19 families and 26 genera. Eight genera of them are also new to Korea, which are Platydictya, Ardeuma, Chenia, Eucladium, Geheebia, Syntrichia, Heterocladium, and Campylostelium. Among about 360 moss specimens of Korea deposited at the herbarium of the TNS, Grimmia longirostris and Brachythecium buchananii var. gracillimum are confirmed as new records based on the specimens collected from Baekdusan Mt. in 1942 and Anbyun, Gangwon-do, North Korea, in 1940, respectively.
Reconfirmed records
Park and Choi (2007) listed new mosses from Korea, but they did not present any references and specimens. We reconfirmed 9 species of them in this study. The asterisk (*) indicates them.
Enumeration
The mosses recognized in this study are listed below. The scientific names follow Frey et al. (2006), Goffinet et al. (2009), and Ignatov et al. (2012). The families, genera and species are arranged alphabetically. Each species is referred by localities, elevation, dates, collector, specimen numbers and range of the distribution.
Amblystegiaceae
1. *Hygrohypnum purpurascens Broth.
Specimen examined: SOUTH KOREA. Gyeonggi-do: Yangju-si, Jangheung-myeon, 37°42′39.1″N, 126°59′41.2″E, elev. ca. 260 m, 27 Jun 2016, NIBRMS106348 (KB).
Distribution: China, Japan, and Korea.
This species was first recorded by Park and Choi (2007), and, they recognized H. purpurascens as a synonym of Hygrohypnum subeugyrium. However, it is based on the dissertation of Jamieson (1976), the taxonomic treatment is not validly published. Therefore, this study recognizes that the correct name is Hygrophypnum purpurascens. Furthermore, Park and Choi (2007) didn’t present any references and specimens. Therefore, the present study first verifies that this species is distributed in Korea.

This species was firstly recorded by Park and Choi (2007), but references are not presented. In this study, it is verified for this species to grow in Jeju Island. Deuguchi et al. (1998) and He and Song (2007) reported V. flaccida and V. montagnei from Ulleung Island. Sometimes, Vesicularia is confused with Ectropothecium. However, Vesicularia has alar cells not or slightly differentiatted and pelucid, and leaf margin entire or slightly serrulate at the apex.
