  • Fifty eight specimens of Ascomycotina were collected at Gwangneung, Mt. Weorak, Mt. Seorak, Mt. Paldal, Mt. Sungsu, Mt. Chiri and Mt. Odae from May, 1989 to October, 1992. These Ascomycotina were identified and classified into 6 orders, 10 families, 19genera, and 29 species. Among them, Peziza michelii(Boud.) Dennis, Tricharina gilva(Boud.) Ekblad, Jafnea fusicarpa (Gerard) Korf, Scutellinia kergulensis(Berk.) O. Kuntze, Vibrissea truncorum Fries, Ciboria amentacea (Balbis ex Fr.) Fuckel, Hypoxylon fragiforme(Per. ex Fr.) Kickx and Nectria episphaeria(Tode ex Fr.) Fries were newly recorded in Korea. These species were described and their Korean names were designated.

  • Lee and author (2000) rearanged the list of mushrooms recorded in Korea, containing 1,554 species 388 genera from 90 families for the systematic classification of Korean mushrooms at Korea Forest Research Institute. In September, 2002, Lee, Tai-Soo and Kab-Hee Yoon made public ‘The Index of Korea-Japan Mushroom names in Korea’ that listed 1,610 species from 396 genera, 90 families and 23 orders of mushrooms recorded in Korea. Among the listed taxa, 1,369 species, 297 genera, 65 families, 15 orders belong to Basidiomycotina and 241 species, 99 genera, 25 families and 8 orders belong to Ascomycotina. A total of 56 species were newly added to the list of recorded Korean mushrooms for a period of 2 years. On the other hand, a total of 75 species, 3 varieties and 2 formae were added to the list of recorded Korean mushrooms by the author, and they were published by many researchers from 2001 to 2004. Among the published taxa, one forma, 20 species, 16 genera, 12 families belong to Ascomycotina and one forma, 3 varieties, 55 species, 33 genera, 17 families belong to Basidiomycotina.

  • Three species belong to the genus Laboulbenia were collected on Carabidae (Coleoptera) and Harpalidae (Coleoptera) from several regions of Korea. Laboulbenia anoplogenii Thaxter was collected from Stenolophus quinquepustulatus Widemann. The characters of this species are the fourth layer of receptacle consisted of two or three cells and the distal end of its posterior cell projecting upward. The thalli were produced on posterior and anterior legs of the hosts. Laboulbenia habui Terada was collected from Chlaenius variicornis Bates. This species is characterized by the basal cells of the secondary appendage composed of short-cylindrical cells, arranged alternately on a double row. The thalli were produced from the elytra and anterior abdomen of the hosts. Laboulbenia pallida Thaxter was collected from Anisodactylus signatus Panzer. This species is distinguished from other related species by the rounded tip of perithecium and the outer appendage branched on the basal cell. The thalli were produced on the posterior elytra of the hosts.

  • The mycobiota of the sandy soil of Egyptian beaches was investigated in thirty six sand samples collected from nine different localities in Egypt. The filamentous fungi were identified and assigned to thirty one genera and fifty one species. Greater populations as well as a wider spectrum range of fungal genera and species were obtained in sandy soil of Alexandria beach while Balteem beach was the poorest one. The total count of the genus or species was not depended upon cases of isolation. Most of the genera detected belonged to the Deuteromycotina with fewer proportions belonging to the Ascomycotina and Zygomycotina. The genera of highest incidence and their respective numbers of species were: Penicillium(35.72%, 6 species) and Aspergillus(30.28%, 16 species). The species which showed the highest incidence in all cases was P chrysogenum, followed by P citrinum, A. flavus, Chaetomium murorum and Trichoderma viride. A few number of other genera and species were also detected.

  • Eight species belonging to two genera of the Laboulbeniales, parasitic on the family Carabidae and Staphylinidae of the order Coleoptera, were collected from Upo natural swamp in 1996-2001. They are as follows; Laboulbenia anoplogenii parasitic on Platynus daimio, L. cristata on Paederus parallelus, L. egens on Tachys laetifica, L. flagellata on Platynus daimio, L. pedicellata on Bembidion morawitzi, L. philonthi on Philonthus wuesthoffi, L. stenolophi on Acupalpus inornatus and Philonthus longicornis, and Peyritschiella biformis on Philonthus micaticollis. Among these species, the genus Platynus as the host of L. anoplogenii and the genus Acupalpus as the host of L. stenolophi are new to science. Bembidion morawitzi as the host of Laboulbenia pedicellata and Philonthus micanticollis as the host of Peyritschiella biformis are new to Korea.

  • In previous studies investigating the genus Xanthoparmelia, thirteen different species have been reported from South Korea alone. However, there currently has been no revisional study performed until now. To explore the genus Xanthoparmelia, a phenotypic analysis was performed based on morphological, anatomical and chemical characters, while an investigation of Xanthoparmelia phylogeny was based on nuclear ribosomal (nr) DNA ITS sequences. A thorough examination of the specimens deposited in the Korean Lichen Research Institute (KoLRI) confirmed that eight species of Xanthoparmelia occur inside South Korea. Our analysis further confirmed the colors of the lower surface and medullar chemistry are important taxonomic characters in Xanthoparmelia. This study also presents a detailed description of each species and a key to the genus.

  • Korean species of the genus Myelochroa are revised taxonomically and the following eight species are recognized: M. aurulenta (Tuck.) Elix & Hale, M. entotheiochroa (Hue) Elix & Hale, M. galbina (Ach.) Elix & Hale, M. hayachinensis (Kurok.) Elix & Hale, M. irrugans (Nyl.) Elix & Hale, M. leucotyliza (Nyl.) Elix & Hale, M. metarevoluta (Asahina) Elix & Hale and M. perisidians (Nyl.) Elix & Hale. Myelochroa ibukiensis K.H. Moon et al. is reduced to a synonym for M. aurulenta. Myelochroa denegans (Nyl.) Elix & Hale, M. indica (Hale) Elix & Hale and M. xantholepis (Mont. & Bosch) Elix & Hale are excluded from the lichen of Korea. In addition, a key for the species of the Korean Myelochroa is provided.

  • Three species of the genus Chitonomyces and one species of the Autoicomyces (Laboulbeniales, Ascomycotina) were newly added to the flora of Korea. They were Autoicomyces bicornis Thaxter, Chitonomyces chinensis Thaxter, Chitonomyces melanurus Peyritsch and Chitonomyces paradoxus (Peyritsch) Thaxter. Descriptions of all species of the Laboulbeniales collected in this country, including their host insects and distribution, were given in this paper.

  • 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.
