To explore species diversity of Hypocreaceae, collections from Guangdong, Hubei, and Tibet of China were examined and two new species and a new Chinese record were discovered. Morphological characteristics and DNA sequence analyses of the ITS, LSU, $EF-1{\alpha}$, and RPB2 regions support their placements in Hypocreaceae and the establishments of the new species. Hypomyces hubeiensis sp. nov. is characterized by occurrence on fruitbody of Agaricus sp., concentric rings formed on MEA medium, verticillium-like conidiophores, subulate phialides, rod-shaped to narrowly ellipsoidal conidia, and absence of chlamydospores. Trichoderma subiculoides sp. nov. is distinguished by effuse to confluent rudimentary stromata lacking of a well-developed flank and not changing color in KOH, subcylindrical asci containing eight ascospores that disarticulate into 16 dimorphic part-ascospores, verticillium-like conidiophores, subcylindrical phialides, and subellipsoidal to rod-shaped conidia. Morphological distinctions between the new species and their close relatives are discussed. Hypomyces orthosporus is found for the first time from China.

The diversity of culturable non-actinobacterial (NA) bacteria associated with four species of South China Sea gorgonians was investigated using culture-dependent methods followed by analysis of the bacterial 16S rDNA sequence. A total of 76 bacterial isolates were recovered and identified, which belonged to 21 species of 7 genera, and Bacillus was the most diverse genus. Fifty-one percent of the 76 isolates displayed antibacterial activities, and most of them belonged to the Bacillus genus. From the culture broth of gorgonian-associated Bacillus methylotrophicus SCSGAB0092 isolated from gorgonian Melitodes squamata, 11 antimicrobial lipopeptides including seven surfactins and four iturins were obtained. These results imply that Bacillus strains associated with gorgonians play roles in coral defense mechanisms through producing antimicrobial substances. This study, for the first time, compares the diversity of culturable NA bacterial communities among four species of South China Sea gorgonians and investigates the secondary metabolites of gorgonian-associated B. methylotrophicus SCSGAB0092.

Arthonia coreana, Arthonia superpallens, and Arthonia zelkovae are new species from South Korea. All new species are in the Euarthonia tribe, based on the key characteristics of colorless hypothecium and multi-cellular spores. A. coreana has a dull brownish hypophloedal thallus without bleaching and rounded or curved big apothecia in comparison with those of Arthonia punctiformis. A. coreana consistently exhibits 4-septate ascospores, which is a distinctive characteristic that distinguishes it from other Arthonia species. A. superpallens has a white-greenish thallus, pale yellowish apothecia, and a trentepohlioid alga. However, A. superpallens has no distinct prothallus, adnate, and convex apothecia, no pycnidia, and is UV-, in contrast with related species in the Arthonia antillarum group. A. zelkovae has a white, epiphloedal thallus, brownish-black epruinose apothecia covered with a whitish bark layer, and smaller ascospores in comparison with those of A. punctiformis. A. zelkovae consists of a chlorococcoid alga, which differs from related Arthonia species such as A. punctiformis, Arthonia pinastri, and Arthonia glaucella. Although A. zelkovae is similar to Arthonia dispersa in its white-colored thallus, blackish apothecia, and the presence of a chlorococcoid photobiont, A. zelkovae differs from the latter in having larger-sized 3-septate ascospores. Arthonia cinnabarina f. marginata, A. glaucella, Arthonia ilicinella, Arthonia lapidicola, Arthonia leioplacella, Arthonia pertabescens, A. pinastri, Arthonia spadicea, and Arthonia stellaris are newly described in Korea. The diagnostic characteristics of these species are discussed and presented. An artificial key is provided to facilitate identification of Arthonia species from Northeast Asia.

Boletus is a symbiotic ectomycorrhizal flesh fungi forming mycorrhizas with trees of Pinaceae, Fagaceae and Betulaceae. The species in the genus have relatively strong host specificity to enhance the growth of host plants and some of them are flavorful. But Korean rarely consumes these kinds of mushrooms and B. edulis has not been reported in this country. In the genus twenty six species have been reported in Korea, but the number is expected to increase as collection efforts are intensified. Keys to the families of Boletaceae and Strobilomycetaceae, to the genus of Boletaceae and to the species of Boletus were provided based on published keys and the descriptions of species reported in Korea. However, the key to the Boletus species did not include all the species occurring in Korea and not all the ones in the key are indigenous.

The leafhopper genus Batracomorphus Lewis, 1834 belongs to the tribe Batracomorphini (Hemiptera: Auchenorrhyncha: Cicadellidae: Iassinae). B. irroratus Lewis, 1834 was designated as its type species. The genus includes most diverse species in the subfamily Iassinae and contains approximately 350 described species from the world. In Korea, four Batracomorphus species, B. allioni (Turton, 1802), B. punctilliger Anufriev, 1981, B. stigmaticus (Matsumura, 1912), B. viridulus (Melichar, 1902), have been reported in the Korean peninsula. The members of this genus have a similar body size and similar general appearances; thus, it is very difficult to identify clearly without examining the male's genital structures. In this study, Batracomorphus furcatus Li and Wang, 2003 is newly reported from Korea for the first time. This species is previously known to be from China. Herein, the morphological information of B. furcatus Li and Wang is provided with a re-description, photographs of the male dorsal habitus, illustrations of the genitalia structure and distributional records. In addition, a key to the Korean five species of Batracomorphus is presented.

Previously, 33 species, 18 genera, eight subfamilies of the family Tineidae were reported in Korea. In this study detail a new record to Korea, species, Micrerethista denticulata Davis, 1998 in the subfamily Harmacloninae in Korea. This species is the most widespread species of the genus in southern Asia, ranging from Thailand through Indonesia to southern Japan but absent from New Guinea. Globally, Harmacloninae Davis, 1998 includes 22 species of two genera. The subfamily can be distinguished from the other Tineidae subfamilies by an additional wing locking mechanism, loss of pretarsal arolium and pseudempodial seta, tympanic organ in abdominal sternum II, enlargement of sternal apophyses, and aedeagus with basal midventral keel in male genitalia. The morphological characteristics of this subfamily and species are described, and illustrations of examined species and the key characters for each subfamilies of the family Tineidae from Korea are provided.

Xanthoria elegans is a lichen symbiosis, that inhabits extreme environments and can absorb UV-B. We reported the de novo sequencing and assembly of X. elegans genome. The whole genome was approximately 44.63 Mb, with a GC content of 40.69%. Genome assembly generated 207 scaffolds with an N50 length of 563,100 bp, N90 length of 122,672 bp. The genome comprised 9,581 genes, some encoded enzymes involved in the secondary metabolism such as terpene, polyketides. To further understand the UV-B absorbing and adaptability to extreme environments mechanisms of X. elegans, we searched the secondary metabolites genes and gene-cluster from the genome using genome-mining and bioinformatics analysis. The results revealed that 7 NR-PKSs, 12 HR-PKSs and 2 hybrid PKS-PKSs from X. elegans were isolated, they belong to Type I PKS (T1PKS) according to the domain architecture; phylogenetic analysis and BGCs comparison linked the putative products to two NR-PKSs and three HR-PKSs, the putative products of two NR-PKSs were emodin xanthrone (most likely parietin) and mycophelonic acid, the putative products of three HR-PKSs were soppilines, (+)-asperlin and macrolactone brefeldin A, respectively. 5 PKSs from X. elegans build a correlation between the SMs carbon skeleton and PKS genes based on the domain architecture, phylogenetic and BGC comparison. Although the function of 16 PKSs remains unclear, the findings emphasize that the genes from X. elegans represent an unexploited source of novel polyketide and utilization of lichen gene resources.
