  • Three species of the genus Xylaria are recognized on Taiwan materials: X. allantoidea (Berk.) Fr. and X. obovata (Berk.) Fr.; including one new record X. curta Fr., having $9.0-10.8{\times}3.9-5.4\;{\mu}m$ ascospores, in Taiwan.

  • Xylaria, belonging to the Ascomycotina, is known to produce diverse classes of bioactive substances. In an effort to identify the chemical constituents of the fruiting bodies of Xylaria polymorpha, linoleic acid (1), linoleic acid methyl ester (2), ergosterol (3), 4-acetyl-3,4-dihydro-6,8-dihydroxy-3-methoxy-5-methyl-1H-2-benzopyran-1-one (4), and 4-hydroxyscytalone (5) were isolated from its methanolic extract. Their structures were assigned on the basis of various spectroscopic studies.

  • Many higher fungi of ascomycetes were collected at Mt.Jiri National Park, Pyonsan Peninsula National Park, Mt. Pangtae of Kangwon-do, Mt. Moak Provincial Park of Chollabuk-do and Mt. Manduck near Chonju city from June 1995 to October 1996. Identification of the revealed that Calycellina, Diatrype and Diatrypella were new genera to Korea and Scutellinia umbrarum, S. pseudoumbarum, Dasyscyphus virgineus. Calycellina punctiformis, Xylaria oxyacanthae, Diatrype disciformis, Diatrypella quercina and D. verrucaeformis were newly to Korea.

  • Abstract Griseofulvin has been used as an antifungal antibiotic for the treatment of mycotic diseases of humans and veterinary animals. The purpose of this work was to identify a griseofulvin-producing endophytic fungus from Abies holophylla and evaluate its in vivo antifungal activity against plant pathogenic fungi. Based on nuclear ribosomal ITS1-5.8SITS2 sequence analysis, the fungus was identified and labeled as Xylaria sp. F0010. Two antifungal substances were purified from liquid cultures of Xylaria sp. F0010, and their chemical identities were determined to be griseofulvin and dechlorogriseofulvin through mass and NMR spectral analyses. Compared to dechlorogriseofulvin, griseofulvin showed high in vivo and in vitro antifungal activity, and effectively controlled the development of rice blast (Magnaporthe grisea), rice sheath blight (Corticium sasaki), wheat leaf rust (Puccinia recondita), and barley powdery mildew (Blumeria graminis f. sp. hordei), at doses of 50 to 150 ${\mu}$g/ml, depending on the disease. This is the first report on the production of griseofulvin and dechlorogriseofulvin by Xylaria species.

  • During a Korean mushroom diversity survey from 2011 to 2014, we found one new Xylaria species (X. ripicola sp. nov.) and one Xylaria species that had not been previously observed in Korea (X. tentaculata). To confirm the phylogenetic placement of the new species, we conducted a phylogenetic investigation based on internal transcribed spacer regions of ribosomal DNA sequences. Additionally, the new species, X. ripicola, was subsequently analyzed for RNA polymerase II subunit sequences. We also evaluated the macroscopic and microscopic features of this species. Herein, X. ripicola is described as a new species that was collected from a natural beach habitat and X. tentaculata is formally reported as newly found in Korea.

  • An endolichenic fungus, Xylaria grammica strain EL000614, showed strong nematicidal effects against plant pathogenic nematode, Meloidogyne incognita by producing grammicin. We report genome assembly of X. grammica EL000614 comprised of 25 scaffolds with a total length of 54.73 Mb, N50 of 4.60 Mb, and 99.8% of BUSCO completeness. GC contents of this genome were 44.02%. Gene families associated with biosynthesis of secondary metabolites or regulatory proteins were identified out of 13,730 gene models predicted.

  • Endophytic fungi were isolated from the leaves of diverse plants inhabiting Jeju Island, Korea. The fungal isolates were identified through phylogenetic analyses incorporating nucleotide sequences derived from the internal transcribed spacer region, large subunit region of ribosomal DNA, and beta-tubulin gene. Our results identified six endophytic fungi previously unknown in Korea namely, Diaporthe goulteri, Diaporthe vaccini, Rhizosphaera pini, Valsa friesii, Xylaria primorskensis, and Zalerion arboricola were identified. Here, we present their cultural and morphological characteristics and phylogenetic relationship.

  • Free amino acids in extracts and total amino acids in hydrolysates of eight species of higher fungi were analyzed by an amino acid autoanalyzer. Twenty amino acids were analyzed in eight species of higher fungi. 1) of all free amino acids contained in higher fungi, alanine is the richest, and then comes glutamic acid, serine, arginine, proline and histidine in that order. Of all total amino acids contained in higher fungi, glutamic acid is the richest, and then comes proline, valine, aspartic acid, alanine, leucine in that order. Especially Russula fragilis and Lepiota procera contain large quantity of glutamic acid. 2) Gross contents of free amino acids in the extracts is high in order of Lepiota procera, Phylloporus rhodoxanthus, Russula fragilis, Tylopilus felleus and total amino acids in hydrolysates is high in Phylloporus rhodoxanthus, Lepiota procera, Russula fragilis, Lentinus lepideus. 3) Total amount of essential amino acids in the extracts was high in Lepiota procera, Phylloporus rhodoxanthus, Tylopilus felleus, Xylaria hypoxylon, Lentinus lepideus, Russula fragilis, Lactarius piperatus and Calocybe gambosa and in the hydrolysates of Phylloparus rhodoxanthus, Russula fragilis, Lepiota procera, Tylopilus felleus, Lentinus lepideus, Lactarius piperatus, Calocybe gambosa and Xylaria hypoxylon in that order, respectively.
