FURTHER RESULTS ON CONSERVATION OF LICHENISED FUNGI IN HUNGARY E. FARKAS 1 , L. LŐKÖS 2 , K. MOLNÁR 1 1 Institute of Ecology and Botany of HAS, H-2163 Vácrátót, Hungary 2 Botany Department, Hungarian Natural History Museum, Pf. 222, H-1476 Budapest, Hungary E-mails: efarkas@botanika.hu, lokos@bot.nhmus.hu, kmcz100@gmail.com Efforts for legal protection of lichens in Hungary from 1999 to 2004 were summarised in a former presentation during the XVIth Symposium of Mycologists and Lichenologists of the Baltic States, Latvia, September 2005. Due to our activities 5 lichen species (Cetraria aculeata, Cladonia magyarica, Usnea florida, Xanthoparmelia pseudohungarica and X. subdiffluens) became protected by law (23/2005(VIII.31) KvVM) in August 2005. Further 3 lichen species of the genus Cladina (C. arbuscula, C. mitis and C. rangiferina) were included in an additional law (18/2008(VI.19) KvVM) for conserving further rare and endangered organisms in Hungary. However, recent studies emphasize that Hungarian populations of these species need taxonomic revision urgently. Our forecast about a better understanding of the importance of biodiversity seems to be fulfilled. We still hope that even more species will gain protection in future and our results in taxonomy will support conservation of lichenised fungi. Acknowledgements.

GAGARINA Laboratory of Lichenology and Bryology, Komarov Botanical Institute of RAS, Prof. Popov Str. 2, 197376 St. Petersburg, Russia E-mail: kvercus@yandex.ru The Gyalectaceae and Coenogoniaceae are families of lichenized ascomycetes. The family Gyalectaceae includes widely distributed species. Coenogoniaceae occur mainly in tropical regions. Morphology and anatomy of these families is poorly investigated. The aim of our research is to study the spore ornamentation and apothecia surface in the lichen families Gyalectaceae and Coenogoniaceae by the method of scanning electron microscopy. Totally twenty four species were investigated. The spores and apothecia were examined and photographed in JSM 63 90 LA scanning electron microscope (SEM). The lichens from families Gyalectaceae and Coenogoniaceae can be divided into five groups on the basis of spore ornamentation: 1) smooth, without ornamentation – Belonia herculina, B. russula, Coenogonium luteum, C. pineti, Gyalecta derivata, G. friesii, G. jenensis, G. kukriensis, G. leucaspis, G. liguriensis, G. schisticola, G. subclausa, G. titovii, G. truncigena, G. ulmi, Pachyphiale carneola, P. fagicola, P. ophiospora, Ramonia luteola; 2) with poorly developed ornamentation – Gyalecta flotovii; 3) slightly verrucose – Gyalecta foveolaris, G. peziza; 4) verrucose – Gyalecta geoica; 5) areolate – Gyalecta nigricans. Some information concerning apothecia surface has been obtained. Margin surface is similar for all studied species. According to the disc surface, species were divided into three main groups:
1. Disc surface waxy-looking – Belonia herculina, B. russula, Coenogonium luteum, C. pineti, Gyalecta foveolaris, G. geoica, G. liguriensis, G. peziza, G. schisticola, G. titovii, Pachyphiale carneola, P. fagicola, P. ophiospora. 2. Disc surface without waxy cover. Paraphyse tips of different shapes are visible on the apothecia surface: 2.1. Capitate – Gyalecta flotovii, G. friesii, G. kukriensis, G. subclausa, G. truncigena, G. ulmi; 2.2. Reticulate – Gyalecta nigricans; 2.3. Crater-like – Gyalecta jenensis; 2.4. Linguiform – Gyalecta derivate. 3. Disc surface with numerous crystals – Gyalecta leucaspis. THE PRELIMINARY RESULTS ON ANTIBACTERIAL ACTIVITY OF EXTRACTS FROM IN VITRO CULTURED MYCELIA OF Protoparmeliopsis muralis B. GUZOW-KRZEMIŃSKA 1 , J. DYBUŚĆ 2 Department of Molecular Biology, University of Gdańsk, Kładki 24, 80-822 Gdańsk, Poland 1 E-mail: beatagk@biotech.ug.gda.pl; 2 e-mail: czaprowska@wp.pl Lichens have been used in folk medicine for centuries. Many secondary metabolites have been identified and isolated from lichens and some of them were found to have antimicrobial activity. Although numerous studies were published on antibacterial activity of metabolites extracted from lichen thalli, mycelial cultures did not get that much attention so far. Antimicrobial activity of in vitro cultured mycelia of Protoparmeliopsis muralis (syn. Lecanora muralis) was tested against Gram-positive and Gram-negative bacteria. We tested acetone and methanol extracts from mycelia grown on PDA and GLBM media. The following bacterial strains were used in disc diffusion tests: Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa and Staphyllococcus aureus. We observed a stronger antibacterial activity against Gram-positive bacteria than Gram-negative strains. Acknowledgements.

LICHENS IN RED DATA BOOK OF LENINGRAD REGION – CURRENT SITUATION AND PERSPECTIVES D. E. HIMELBRANT, E. S. KUZNETSOVA, I. S. STEPANCHIKOVA Department of Botany, St. Petersburg State University, Universitetskaya Emb. 7/9, 199034 St. Petersburg, Russia Laboratory of Lichenology and Bryology, Komarov Botanical Institute of RAS, Prof. Popov Str. 2, 197376 St. Petersburg, Russia E-mails: d_brant@mail.ru, igel_kuzn@mail.ru, stepa_ir@mail.ru The first edition of Red Data Book (RDB) of Leningrad Region (LR) was published in 2000. The list of lichens includes 49 species. At that moment it was about 7% of known lichen diversity in the region (Zavarzin et al., 1999). At present we have data about approximately 950 species inhabiting LR (e. g. Kuznetsova, 2007; Stepanchikova et al., 2009, 2010). It means that only 5% of lichens are protected. The species were included in RDB according to the following criteria: 1) species listed in RDB of RSFSR (1988); 2) species that need protection throughout LR; 3) rare species
