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

The new genus and species, Jejulea byssolomoides, 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 lm diameter, 200–250 lm 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 Jejulea in the Pilocarpaceae (Lecanorales). The new taxon is closely related to Byssoloma, a cosmopolitan group of foliicolous lichens, which is most diverse in the tropics. Like Byssoloma, Jejulea also forms a byssoid apothecial margin.

Endocarpon subramulosum (Verrucariaceae) a New Species of Lichenized Fungi from South Korea

In this paper, we describe Endocarpon subramulosum as a new species from temperate regions of South Korea, which grows over soil on rocks. The proposed new species is morphologically similar to E. ramulosum Harada, which has so far been reported from Japan.

A Lichen Genus Porpidia (Porpidiaceae) from South Korea

Taxonomic study of the crustose lichen Porpidia was performed in this paper. Three species are described, including two recorded species and one new record: Porpidia macrocarpa (DC.) Hertel & A. J. Schwab. A description of each species is presented along with morphological, anatomic, and chemical characteristics. A key to the identification of species of Porpidia is also presented.

Dactylospora glaucomarioides (Ascomycetes, Dactylosporaceae): A Lichenicolous Fungus New to South Korea

The lichenicolous fungi flora of South Korea is poorly known. During recent field trips to various parts of South Korea and after an extensive examination of herbarium lichen specimens, we encountered a lichenicolous fungi growing over a thallus of the lichen Ochrolechia yasudae Vain., characterized by small black apothecia with mostly three-septate brown ascospores. It was identified as Dactylospora glaucomarioides. This is the first report of this lichenicolous fungus from South Korea. A taxonomic description and comments are presented.

Identification of Sculptolumina japonica (Physciaceae) in South Korea

The paper describes identification of new microlichen (Sculptolumina japonica) in South Korea. A detailed taxonomic description and comments are presented for the taxa studied. Lichen genus Sculptolumina is reported for the first time for this country.

Notes on Lichen Genus Buellia De Not. (lichenized Ascomycetes) from South Korea

Based on a literature survey and assessment of the important features of lichen genus Buellia (spore shape and size, anatomy of the exciple as well as analysis of the lichen substances), the present paper describes four new records of B. maritima, B. polyspora, B. spuria and B. stellulata from South Korea. Among them, B. maritima and B. polyspora are firstly reported in East Asia including in China, the Korean Peninsula and Japan. Brief description of all the new records along with earlier described species placed under genus Amandinea and Hafellia are provided with their distribution and chemistry. A key to all the Buellia species reported so far from South Korea is also provided.

Notes on the Existence of Leucodecton desquamescens (Thelotremoid Graphidaceae) in South Korea

This study describes a new record of a thelotremoid lichen (Leucodecton desquamescens) from South Korea. The taxon is characterized by thick, bulging thallus with many calcium oxalate crystal inclusions; an immersed, round to irregular ascomata with free exciple, ellipsoid to +/- roundish submuriform, brown ascospores, and lack of secondary metabolites. A detailed taxonomic description and comments are presented for this taxon. The lichen genus Leucodecton is reported for the first time in South Korea.

New Record of the Existence of Sarcographa tricosa (Lichenized Ascomycota, Graphidaceace) in Korea

Lichen genus Sarcographa Fee, a stromatoid Graphidacean taxa, was newly found in Geomun Island, Jeonnam province. The lichen grew on the bark of Camellia japonica and Eurya emarginata along the coastal line of the island. It was identified as Sarcographa tricosa (Ach.) Mull. Arg. for the first time in Korea.

Notes on Some New Records of Macro- and Micro-lichens from Korea

The paper describes nine new records of macro- and micro-lichens from Korea. A brief taxonomic description and comments are presented for all the studied taxa (Catapyrenium squamellum, Chrysothrix candelaris, Endocarpon pallidulum, Endocarpon petrolepideum, Lecanora oreinoides, Leprocaulon albicans, Parmotrema saccatilobum, Verrucaria glaucina and Xanthoria parietina). The lichen genera Catapyrenium, Chrysothrix and Verrucaria are reported for the first time in this country.
