IMC7 Main Congress Theme I: BIODIVERSITY AND CONSERVATION Posters provide a range of micro-habitats and plant communities. Since October 2000, lichens were collected from 13 National Parks in Thailand. These sites were from the far south (Hala Bala at sea level) to the far north (Doi Inthanon at 2,565 metres above sea level). These collections yielded 1116 samples classified into crustose 80%, foliose 14%, fruticose 1%, others 2% and unidentified 3%. These have been identified to 2 orders including 14 families, 32 genera and over 150 species. Common genera of crustose lichens were Graphis, Haematomma, Laurera and Lecanora. Foliose genera included Heterodermia, Parmotrema and Phyllopsora. Cladonia and Usnea were common examples of fruticose genera. Canoparmelia and Hypotrachyna were notable rarities of foliose lichen. Isolations were made from ascospores by direct streaking of spores and spore discharge. 592 - Lignin degrading enzymes of Xylariacious fungi in Thailand P. Srikitikulchai * & E.B.G. Jones BIOTEC-Fermentation Laboratory, National Center for Genetic Engineering and Biotechnology, National Science and Technology Development Agency, 113 Pahonyothin RD., Khlong 1, Khlong Luang, Pathum Thani 12120, Thailand. - E-mail: prasert@biotec.or.th Thailand supports a rich diversity of xylariaceous ascomycetes, with most occurring on wood, although a number have been found on leaves, elephant dung, fruits and seeds, while others have been shown to be endophytes of forest trees (Thienhirun, 1997; Whalley et al. 1995). Nineteen genera in the Xylariaceae have been documented for Thailand with a total of 91 species. However, some 15 Hypoxylon and 30 Xylaria species await description (Thienhirun, 1997). Members of the Xylariales are active degraders of timber in nature and have been shown to cause soft rot and white rot attack of wood. However, little is known about the enzymes they produce. We have screened 51 strains of xylariaceous fungi over the past 2 years for their lignin degrading enzymes. For this study we have used Poly R-478, ABTS and azure-B medium to screen for general lignin degrading enzymes, laccase and peroxidase activity, respectively. Ninety four percent of the isolates gave positive results for laccase, 21% positive for peroxidases, while 43% decolourized the dye Poly-R 478. 593 - Fungal diversity on woody substrates in Scandinavia J.N. Stokland 1* & A. Dahlberg 2 1 Norwegian institute of land inventory, P.O.Box 115, 1430 Ås, Norway. - 2 Swedish Species Information Centre, P.O.Box 7007, SE-750 07 Uppsala, Sweden. - E-mail: jns@nijos.no 180 Book of Abstracts Species diversity patterns have been derived from speciesspecific information of more than 1500 species of Ascomycetes, Heterobasidiomycetes and Basidiomycetes. Several functional associations to woody debris were defined, including primary parasite, primary saprotroph, secondary myco-parasite, secondary myco-saprotroph, and mycorrhiza species (using wood for sporocarp production). Most species are probably primary saprotrophs, but all functional associations are represented. Most species are associated to either coniferous (40%) or hardwood hosts (40%), but many are host generalists (20%). Most taxonomic groups exhibit this pattern, but at least the Ascomycetes show an elevated species richness on hardwood hosts. The degree of decomposition of the wood is important and four patterns were found: early decay preference (less than 10%), medium decay preference (50%), late decay preference (15%) and no decay preference (25%). These proportions varied across taxonomic groups. The dimension of woody substrates is a third factor that many fungi respond to. One group prefer small dimensions (twigs and thin stems) and another is strongly associated to trunks of large dimensions, but the majority of the species (60%) show no strong dimension preference. There are additional factors that woodinhabiting fungi respond to like sun exposure/shade, part of the tree and standing/lying. For these factors there are major knowledge gaps that prevent compilation of diversity patterns. 594 - Lichenicolous fungi in Estonia A. Suija Institute of Botany and Ecology, University of Tartu, 38 Lai Str., Tartu, 51005, Estonia. - E-mail: avesuija@ut.ee The history of floristical investigation of lichen-habiting fungi in Estonia is short. Until the 1990s, only two lichenicolous fungi (Athelia arachnoidea and Rimularia insularis) were known from Estonia. During the last five years, 69 species from 47 genera of these fungi have been registered from Estonia. Most of the lichenicolous species are ascomycetes (45 species); fewer are deuteromycetes (23) and basidiomycetes (7). The most species-rich genera are Abrothallus (5 species), Licheniconium (4), Muellerella (3), Stigmidium (4) and Tremella (4). Most species are categorized as very rare i.e. known from one or two localities in Estonia. Still, there are some exceptions. The distribution area of the basidiomycete Athelia arachnoidea, an aggressive parasite of different protococcoid algae and lichens, has extended since the 1940s. Since the 1990s, this species is especially widespread in towns, roadsides etc. The deuteromycete Vouauxiella lichenicola, a parasite of Lecanora chlarotera and allied taxa, was reported as very rare in 1999. However, the species is now found in about 30 places and its distribution partially coincides with the distribution of Lecanora chlarotera.
IMC7 Main Congress Theme I: BIODIVERSITY AND CONSERVATION Posters 595 - Interesting ascomycetes on Juncaceae and Apiaceae collected in the Czech Republic M. Suková National Museum, Mycological Department, Václavské nám. 68, 11579 Praha 1, Czech Republic. - E-mail: marketa.sukova@nm.cz Saprotrophic ascomycetes and mitosporic fungi on Juncaceae and Apiaceae in the Czech Republic were collected and studied during the years 1997-2001. Eightyfive species belonging to 56 genera were found. Fifteen of these species are reported from the Czech Republic for the first time. They include representatives of Helotiales (Hysteropezizella diminuens, Mollisia fusco-paraphysata, Naeviopsis carneola, Scutomollisia stenospora), Pleosporales (Lophiotrema grandispora, Nodulosphaeria mathieui, N. spectabilis), Mycosphaerellales (Mycosphaerella hypostomatica), and mitosporic fungi (Arthrinium cuspidatum, Chalara urceolata, Coremiella cubispora, Dendryphiella vinosa, Phragmocephala prolifera, Pyricularia juncicola, Stachybotrys cylindrospora). The most interesting species are discussed and illustrated. 596 - NITE Biological Resource Center (NBRC), a newly established biological resource center in Japan K. Suzuki & S. Iwamoto * NITE Biological Resource Center, National Institute of Technology and Evaluation, 2-5-8, Kazusakamatari, Kisarazu, Chiba 292-0812, Japan. - E-mail: iwamotosusumu@meti.go.jp According to the report of OECD, biological resource centers (BRCs) are an essential part of the infrastructure underpinning life sciences and biotechnology. NITE, a non-profit institute under Ministry of Economy, Trade and Industry, has established a new biological resource center, NBRC with the following concept: NBRC is to preserve and supply the cultures of reference microorganisms including fungi, yeasts, bacteria and archaea as an essential function of a culture collection. NBRC isolates, characterizes and develops the original biological resources for its own collection. In addition, NBRC also provides DNA and clones based on the genomic sciences. To access the appropriate resources, NBRC develops advanced databases containing application data and taxonomic data. As the so-called intelligent administration, NBRC have to take care of the ownership of the biological resources to encourage the deposit of valuable resources. Convention for Biological Diversity should be considered when biological resources are transferred between countries. Based on these, NBRC intensively make international cooperative studies with the resource countries especially in the South East Asia to produce benefits for both sides. 597 - Taxonomical investigations of Hungarian protected fungi Gy. Szedlay 1* & I. Siller 2 1 Eötvös University, Dept. of Plant Anatomy, 1117 Budapest, Pázmány P. s. 1/c, Hungary. - 2 Szent István University, Dept. of Botany, 1074 Budapest, Rottenbiller u. 50., Hungary. - E-mail: szedlay@ludens.elte.hu In the last decades fungal taxonomy has undergone enormous change. The traditionally used morphological description of species has been completed with molecular and interfertility results. We examined phylogenetic relationships of the holotypes of fungi described in Hungary using morphological and molecular methods (DNA sequencing). Species of Agaricus, Leucoagaricus, Macrolepiota, Lepista and Cortinarius genera were investigated. In some cases our results confirmed, in others questioned the isolation of the examined species from their near relatives. 598 - Diversity of fungi on wild fruits in Hong Kong A.M.C. Tang The University of Hong Kong, 2N-16 Kadoorie Biological Science Building, The University of Hong Kong, Pokfulam Road, Hong Kong, China. - E-mail: alvtang@hkem.com The postharvest diseases of cultivated fruits have been well studied, however, there have been few surveys of the diseases of wild fruits. Small fleshy fruits are of special interest due to the potentially conflicting relationship with frugivorous birds and microbes. The fruits need to attract dispersers after ripening but repel microbes. In the current survey, 15 species of wild fruits were examined from the mature stage to the senescent stage for visible symptoms and signs of diseases in the field and after incubation. Half of the fruit samples were also surface-sterilized to eliminate surface fungi. A total of 104 fungal taxa have been isolated so far, including 21 ascomycetes, 57 coelomycetes and 24 hyphomycete. The most common ascomycete genera were Gaeumannomyces, Guignardia and Massarina spp. and the most common mitosporic genera were Cladosporium, Colletotrichum, Penicillium, Pestalotiopsis, Phoma, and Phomopsis spp. Book of Abstracts 181
