The Revision of Lichen Flora Around Maxwell Bay, King George Island, Maritime Antarctic.

Since the floristic study of lichens at the Barton and Weaver Peninsulas of King George Island in 2006, there have been intense investigations of the lichen flora of the two peninsulas as well as that of Fildes Peninsula and Ardley Island in Maxwell Bay, King George Island, South Shetland Islands, maritime Antarctic. In this study, a total of 104 species belonging to 53 genera, are identified from investigations of lichens that were collected in austral summer seasons from 2008 to 2016. Phenotypic and molecular analyses were incorporated for taxonomic identification.

gen. et sp. nov., a Remarkable (Lichen-Forming Ascomycetes) from Jeju Island, South Korea.

The new genus and species, is described from Jeju Island, Korea. This lichen is characterized by saxicolous, crustose, pale greenish-gray, partly finely filamentous, matt, smooth thallus, prominent convex brown to dark brown ascomata with a concolorous margin constricted at the dark brown base, 300-800 μm diameter, 200-250 μm high, without a distinct proper margin, adhering to the substratum ending in a minute byssoid white external part of cylindrical cells, fusiform 3-5 septate ascospores (17-23 × 4-5 μm). Phylogenetic analyses using ITS and mtSSU sequences place in the (Lecanorales).

Two New Lichen Species, and from Korea.

Two new species, and are described from Ullung-Do (Island), South Korea. The closest relatives from Europe and Korea are epiphytic which differs by their immersed or semi-immersed yellow ascomata, ascospores without halo and their habitat of smooth bark (mainly Fagus) in humid and cold climates. differs by its bigger semi-immersed ascomata (600-700 µm in diam.

and - Two New Taxa from Dokdo Islands (South Korea).

sp. nov., a lichenicolous fungus from the subcosmopolitan complex growing on crustose thalli of species of the genus (subfamily Xanthorioideae, Teloschistaceae), as well as the lichen species sp.

Two New Corticolous Buellioid Species from South Korea.

Several buellioid specimens were collected from South Korea during field surveys and two new species are described based on morphology, chemistry, and molecular phylogeny. sp. nov.

Biodiversity in remnants of natural mountain forests under conservation-oriented management.

The structure of forests is an important stabilizing factor regarding ongoing global climate and land use change. Biodiverse mountain forests with natural structure are one of the ecosystems most endangered by these problems. We focused on the mountain forest islands of European beech (Fagus sylvatica) and their role in the natural distribution of organisms.
