Four new species of Ashmead (Hymenoptera, Bethylidae) from Korea with an updated key to species in the Eastern Palaearctic region.

The genus Ashmead, 1893 (Hymenoptera, Bethylidae) is a cosmopolitan bethylid genus with 68 valid species distributed across most zoogeographic regions worldwide. This taxonomic study on Korean species of has led to the description of four new species, namely , , , and Additionally, illustrations of the diagnostic characteristics of each species are provided, along with an updated key for 11 species from the Eastern Palaearctic region.

Diversity of (Cladosporiales, Cladosporiaceae) species in marine environments and report on five new species.

species are cosmopolitan fungi, characterized by olivaceous or dark colonies with coronate conidiogenous loci and conidial hila with a central convex dome surrounded by a raised periclinal rim. species have also been discovered in marine environments. Although many studies have been performed on the application of marine originated species, taxonomic studies on these species are scarce.

Taxonomic study of (Omphalotaceae, Agaricales) in the Republic of Korea with seven new species.

is a genus of the gymnopoid/marasmioid complex of the family Omphalotaceae. The classification system of has recently undergone large changes through molecular approaches. The new classification system has not been applied for in the Republic of Korea, and general research on this genus was also lacking.

Vascular plants occurrences in Dokdo Islands, Korea, based on herbarium collections and legacy botanical literature.

Background: The vascular flora of the Dokdo Islands has been reported, based on primary collections made in 2012 and 2013 and legacy botanical literature. The Dokdo Islands are the remotest islands of Korea, located in the East Sea approximately 87 km from Ulleungdo Islands. They comprise two main volcanic islands, Dongdo (east islands) and Seodo (west islands) and minor islets surrounding the two main islands.

Historical collections of vascular plants in the Korean Peninsula by three major collectors in the early 20th century: U. J. Faurie, E. J. Taquet and E. H. Wilson.

Background: The digitisation of historical collections aims to increase global access to scientific artifacts, especially those from currently inaccessible areas. Historical collections from North Korea deposited at foreign herbaria play a fundamental role in biodiversity transformation patterns. However, the biodiversity pattern distribution in this region remains poorly understood given the severe gaps in available geographic species distribution records.
