  • 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.

  • Seventy-two lichen specimens of Cetrelia collected in South Korea since 2003 were examined by both phenotypic and phylogenetic analyses. The phenotypic analysis was based on morphological and chemical characters, and the phylogenetic analysis was based on nrDNA ITS sequences. The result suggested that the presence and absence of isidia, soredia, lobules and medullar reaction C+ or C- are the important characters in the taxonomy of this genus. Four species of Cetrelia, C. chicitae, C. braunsiana, C. japonica, and C. pseudolivetorum have been identified in this study. Description of each species is presented with morphological and chemical characters. A key to the Cetrelia species is also presented.

It is characterized by short and slender podetia with verruculose surface, split along the sides. Apothecia large, pale brown, always growing on the top of the podetia. Primary squamules shell-like, thick, and convex. Fumarprotocetraric acid contained in thallus. This is the first record of this species in Korea.

  • Heterodermia squamulosa (Degel.) W.L. Culb. was found in the mountain of Gariwang, Gangwon province, in 2008. It is characterized by numerous squamules along the margin, decorticate and white lower surface, rhizines along the margin, black and densely squarrosely branched, usually forming a dense mat under the thallus. Apothecia margins densely squamulose, ascospores $12\sim15\times25\sim30{\mu}m$. Atranorin and zeorin contained in thallus. This is the first record of this species in South Korea.

  • In this study, endophytic fungi were isolated from the leaves of evergreen woody plants in Hansando Island in South Korea. The fungal isolates were identified based on morphological characteristics and phylogenetic analysis of the DNA sequences of the internal transcribed spacer and the large subunit regions of rDNA. It was confirmed that two endophytic fungal species, Muyocopron lithocarpi and Didymocyrtis cladoniicola, isolated in this study have not previously been reported in South Korea.

  • Collema Weber ex F.H. Wigg is scarcely scattered throughout South Korea. However, a detailed taxonomic or revisionary study has not been carried out for almost two decades. The present study was based on specimens deposited in the lichen herbarium at Korean Lichen Research Institute, which were identified using recent literature. In this revisionary study, a total of sixteen species of Collema, including five new records, C. furfuraceum var. luzonense, C. pulchellum var. subnigrescens, C. rugosum, C. subconveniens, C. tenax, and one variety C. leptaleum var. leptaleum were documented. Further, detailed descriptions of each species and their morphological, anatomical and chemical characteristics and a key to all known Collema species of South Korea were reported.

  • Scopulariopsis brevicaulis is a widely distributed soil fungus known as a common saprotroph of biodegradation. It is also an opportunistic human pathogen that can produce various secondary metabolites. Here, we report the first complete mitochondrial genome sequence of S. brevicaulis isolated from air in South Korea. Total length of the mitochondrial genome is 28,829 bp and encoded 42 genes (15 protein-coding genes, 2 rRNAs, and 25 tRNAs). Nucleotide sequence of coding region takes over 26.2%, and overall GC content is 27.6%. Phylogenetic trees present that S. brevicaulis is clustered with Lomentospora prolificans with presenting various mitochondrial genome length.

  • The fruiting bodies and roots of a Tuber species were collected from the rhizosphere of Quercus dentata in Pohang, Korea. The morphological characteristics of the ascoma and ectomycorrhizal roots were studied, and phylogenetic analyses were performed using the sequences of the internal transcribed spacer, large subunit rDNA, and β-tubulin DNA. Based on the features of the fruiting bodies, the species was identified to be Tuber huidongense, which has not been reported earlier in Korea. The morphological characteristics and phylogenetic analysis of T. huidongense are described in the present study.

  • Two new species, Thelopsis ullungdoensis and Phylloblastia gyeongsangbukensis are described from Ullung-Do (Island), South Korea. The closest relatives from Europe and Korea are epiphytic Thelopsis flaveola 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. Thelopsis gangwondoensis differs by its bigger semi-immersed ascomata (600-700 ㎛ in diam.), oblong halonate ascospores (8-12 × 6-8 ㎛) and its habitat of smooth bark of deciduous trees. P. gyeongsangbukensis differs from its relatives within the genus in having 5-septate ascospores (22-26 × 6-8 ㎛), semi-immersed, subglobose ascomata with a flattened top (250-400 ㎛) and a thin, matt, uneven gray-brown to gray-green continuous thallus without isidia.

  • In 2017, Talaromyces variabilis was isolated during a survey of fungal diversity in field soils in Korea. This isolate was described based on its morphological and molecular characteristics and it was identified molecularly using the partial 18S-ITS1-5.8S-ITS2-28S rDNA region and calmodulin (CaM)-encoding gene sequence data. Thus, this study reported morphological and multigene sequence characterization of T. variabilis.
