Lectures are given in the Czech language, but could be done in English too. Lichens are not a systematic group,
therefore a biological view of various aspects of their life (growth, reproduction and dispersal, lichen chemistry),
introduction in lichen physiology and ecology as well as phenomenon of symbiosis and its various forms,
principles of lichen taxonomy and the integration of lichenized fungi into a natural phyllogenetical system are main
topics of the course. Practicals are an integral part of the course and are focused on various forms of fungus-alga
associations, lichen thallus morphology, sexual reproduction and vegetative propagules, secondary lichen
products and using of identification methods.
Course for students of cryptogamology as well as other specializations in botany.
