Numerical taxonomic studies were carried out in order to elucidate the taxonomic relationship among 17 species belonging to Paris. Eighteen characters including 10 morphological, 4 pollen morphological, 2 cytotalonomical and 2 habitat characters were used for the analysis. On basis of UPGMA clustering analysis, two subgenus and seven groups were recognized. The classification of the two subgenus was different from the opinion of subgenus Daiswa and subgenus Paris by Li Heng. The classification of sect. Dunnianae, sect. Axiparis and sect. Paris was correspondence with the classification of Li Heng. But sect. Fargesianae, sect. Marmoratae and sect. Thibeticae which were established based on the especially characters by Li Heng were put into cluster 2, cluster 3 and cluster 4.

The genus Candelaria is characterized by a micro-foliose to micro-fruticose thallus and contains eight species, two of which were reported in South Korea. During the excursion of a Korean lichen flora investigation, some suspected Candelaria concolor specimens were collected, and their morphological, chemical, molecular phylogenetic, and geographic analyses were conducted. The samples eventually proved to be a new species, Candelaria asiatica, which can be recognized by a small, yellow lobate thallus with a pulverulent surface, and a fragile lobe margin with blastidia or phyllidia-like lobules.

Lichen genus Stereocaulon (Schreb.) Hoffm is distributed throughout the world. Although 15 Stereocaulon species have been recorded in Korea, no detailed taxonomic or revisionary research has been conducted for nearly two decades. In this study, we collected 260 putative Stereocaulon spp. samples and identified the species based on morphological, chemical, and molecular characteristics. From the collected samples, 10 species of Stereocaulon were identified, nine of which had already been reported, although this was the first report for the tenth, S. octomerellum Hue, in Korea. General characteristics of Stereocaulon spp. include coralloid phyllocladia and tubercular cephalodia; however, the specimen first collected in Korea was a rare species with tomentum on the pseudopodetia. The specimen of S. octomerellum is characterized by the presence of a primary thallus, granule to short coralloid phyllocladia, and pseudopodetia up to 1 cm in size, with tubercular cephalodia. To determine the phylogeny of the specimens, we compared the ITS sequences of ribosomal DNA and the β-tubulin gene sequences. Phylogenetic analysis showed that the Korean Stereocaulon species were monophyletic and placed in the previous phylogenetic classification. Species of S. intermedium and S. exutum, however, were polyphyletic, and are morphologically variable and widespread species. Overall, we present here detailed morphological and chemical descriptions of each species identified and a revised key of all known Stereocaulon species in South Korea.

We encountered an unfamiliar ascomycete fruiting body, fitting characteristics of the genus Kretzschmaria, which features in a stipitate ascigerous stroma with carbonaceous interior and disintegrating perithecia. In this study, we report and characterize a new species of the decaying fungus. Compared to other species, one of the notable features of this specimen (TPML150908-046) is its stromatal size (up to 15 cm). Although TPML150908-046 is morphologically similar to K. milleri and K. sandvicensis, it differs sharply from both species in apical ring size (TPML150908-046, 6.5~10.5 µm; K. milleri, 11~16 µm) and ascospore width (TPML150908-046, 10.5~17 µm; K. sandvicensis, 8.5~11.5 µm). Phylogenetic trees based on β-tubulin, ITS, and RPB2 sequences showed that our collection clustered with K. sandvicensis, with the respective similarities for these sequences being 95.6%, 91.3%, and 97.7%, signifying it as another species. With these results, we report it as a new species, which we call Kretzschmaria quercicola sp. nov.

Gymnopus is a cosmopolitan genus of agaric fungi and consists of ~300 species. In Korea, Gymnopus represents common saprobic mushrooms, and 12 species have been reported in Korea. Several Gymnopus specimens were collected in Korea between 2008 and 2015. To identify them exactly, phylogenetic analysis was performed by means of the internal transcribed spacer region of ribosomal-DNA sequences from the collected Gymnopus specimens. Among them, G. iocephalus, G. polygrammus, and G. subnudus have not been reported in Korea. A phylogenetic tree and images are provided.

Two new records of Trichocomaceae, namely Aspergillus allahabadii and Penicillium sizovae, were isolated in 2016 during a survey of fungal diversity in different crop fields locations in Gyeongnam, Korea. These species were identified based on morphological characters and phylogenetic analysis using internal transcribed spacer region and β-tubulin-encoding gene sequence data. A. allahabadii and P. sizovae have not yet been reported in Korea. Thus, this is the first report of these species in Korea, and their descriptions as well as details of their morphological characters are presented.
