This study by supervisor I.A. Smirnov explores the role of imperfect fungi in the symbiotic relations of lichen mycobiont and photobiont, focusing on Cladonia mitis and Cetraria islandica. Goals include determining soil micromycetes in lichens and soil, comparing micromycetes species in different lichen types, and examining the impact of bacteria and imperfect fungi on the symbiotic relationship. The research found multiple bacterial forms and micromycete species in lichens, with varying distribution patterns, higher microbial quantities in certain lichen parts, and differences between Cladonia mitis and Cetraria islandica samples. Key identified species include Trichoderma, Penicillium, Fusarium, and Aspergillus.

Participation of Imperfect Fungies in the Symbiotic Relations of a Lichen Mycobiont and Photobiont on the Example of Cladonia mitis and Cetraria islandica presented by supervisor of studies: I. A. Smirnov
Goal Tasks • determine the number of soil micromycetes from lichens and in soil under it • compare the species composition of micromycetes of different types of lichens • determine the relationship between bacteria and micromycetes • to examine the effect of bacteria and imperfect fungi on symbiotic relationship of the fungus and lichen
What is a lichen? lichen mycobiont photobiont ?
Methods 5 4 3 2 1
Conclusions • in lichens occur at least 3 forms of bacteria and 9 species of micromycetes • in lichens dominate bacterial forms • in samples dominate spore forms • quantity of organisms is higher in the apical parts of the thallus • in CladoniaMitisnumber of microorganisms is higher than in CetrariaIslandica • numbers of light-and dark-colored forms in the soil under the lichen are in equal amounts • in our study were found species: Trichoderma, Penicillium, Fusarium, Aspergillus
